The amount of organic matter produced represented the total photosynthesis rate. This was because the total photosynthesis rate reflected the total amount of organic matter produced by the plant through photosynthesis, while the net photosynthesis rate was the value of the total photosynthesis rate minus the respiratory rate, indicating the amount of organic matter accumulated by the plant's photosynthesis.

There were many situations where organic matter did not completely react. The following were some of the relevant manifestations: 1. ** Incomplete combustion reaction ** - The carbon in organic matter (especially in the case of the carbon dioxide) has a negative valency, and it is oxided by oxygen during combustion. When there is insufficient oxygen (incomplete combustion), C will only be oxided to 0, and black carbon (C) will be produced. The products of incomplete combustion can continue to react with oxygen (without adding a catalyst). In addition to the possibility of carbon being produced by incomplete combustion, when organic matter contains elements such as N, the incomplete combustion products may also include NO, N O, etc. 2. ** Incomplete reactions in organic chemistry (side reactions)** - Most organic chemical reactions were complicated and often accompanied by side reactions. For example, under 70 atmospheric pressure, a catalyst, and 170 - 200 ° C, the air was used to produce sulfuric acid, but there were still by-products such as Formic acid and Propionic acid. This indicated that it was often difficult to completely follow the ideal reaction in order to obtain a single product in an organic reaction. There were cases where incomplete reactions led to the formation of multiple products. When writing an organic chemical reaction equation, one couldn't use an equal sign like an organic chemical reaction. Instead, one had to use an arrow because one only needed to write the main products in the reaction, and it was difficult to write all the products. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The dehydration reaction of organic matter was an important knowledge in organic chemistry. The following is a summary of some common types of organic dehydration reactions: 1. ** Dehydrating to ene **: Under the effect of concentrated acid, an alcohol containing a hydrogen atom on the carbon atom adjacent to the carbon atom of the hydrogen atom will undergo an molecular dehydration reaction to form a compound containing a C=C bond. This is an elimination reaction. 2. ** Dewatering to ether **: Dewatering between alcohol molecules will form ether compounds containing O, which is a substitution reaction. 3. ** Dehydrating to Andride **: Under the effect of concentrated H <anno data-annotation-id ="0000004 - 4c64 - 4c64 - 4c64 - 9c6b666c33a"></anno>, the acidic acid will undergo either intermolecular or intermolecular dehydration to form an acid dioxide. 4. ** Dehydrating into Peptides **: The dehydration between the molecules of the ammo acid can form a peptide-like compound containing a peptidic bond. Correspondingly, when a peptide-type compound (including a protein) was subjected to the water digestion, the peptide-bond was always broken to form the corresponding ammo acid. 5. ** Dehydrating into fat **: According to the law of "acid dehydrating alcohol dehydrating", various esters can be formed between the acid and alcohol, or between the molecules of the acid. include that formation of chain ester, ring ester, lactones, and the like. Correspondingly, the ester bond was always broken when the ester was being digested, and the corresponding Carboxyls (or Carboxyates) and Alcohol (or Phen) were formed. 6. ** Dehydrating and carbonizing **: The concentrated sulfuric acid will capture the hydrogen and oxygen atoms in some organic matter in a ratio of 2:1 to carbonize it. In the middle school stage, the elimination reaction could not occur with the alcohol, and not all the alcohol or the substituted alcohol could undergo the elimination reaction. Dewatering reactions included both inner-molecular dehydration (elimination reaction) and intermolecular dehydration (substitution reaction). However, it was important to be precise when describing the types of organic reactions. For example, the reaction between alcohol molecules to form ether was precisely a substitution reaction. It could not simply be called a dehydration reaction. At the same time, it could not be applied to organic reactions using the type of an organic reaction. In addition, the condensation condensation reaction is a reaction between organic compounds containing two functional groups, such as dicarbonic acid and dibasic alcohol, or a reaction between organic compounds containing two functional groups, such as a mixture of both a functional group and a functional group. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The conditions for the organic matter to undergo an oxidization reaction: first, there must be functional groups that can be oxided (such as a hydrogen radical, a carbon-carbon double bond or triple bond, and an aldo group). Secondly, there must be a suitable oxidiser (the aldo group only needs a weak oxidiser, such as silver amine solution, and copper dioxide; double bonds, triple bonds, or alcohol require a strong oxidiser, such as KMn <anno data-annotation-id ="0444433 - 404a-4666666666677"> O </anno>+ catalyst). The conditions for the reduction reaction of organic matter: In addition to the ester and the ester, it contains an unsaturated bond (such as alkyne, alkyne, and other aromatic compounds, as well as aldol). Under heating conditions, it can be reduced by the use of Ni and H <2>. (This answer only applies to high school organic reactions) <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The conditions for different organic substances to react with acid and base were different: - When the organic matter is a ether, it can react with a base. - Carboxic acid can react with bases. - In the water solution, the halalocarbon would react with the alkali-like water, and in the alcohol solution, it would react with the alkali-like alcohol. - Esters can be subjected to the reaction of acid or base. Under base conditions, the reaction is slow when not heated, but the reaction is accelerated when heated. Under acid conditions, it is usually diluted acid and the reaction occurs when heated. - An organic compound with both acid and base functional groups (such as an acid, a protein, etc.) can react with both acid and base. - The silver mirror reaction can occur in the presence of organic substances (such as alkyls) that contain " - The dehydration reaction of alcohol required concentrated sulfuric acid as a catalyst and an absorbing agent, and the reaction was carried out under acidic conditions. - Oils and fats are ester substances, which can undergo a water decomposition reaction under acid or base conditions. - The acidic organic matter and the basic organic matter would undergo a neutralizing reaction. The basic organic matter generally had the characteristic group of an amine group, while the acidic organic matter generally contained a Carboxyl group or a alcoholic group. Some of them only had a alcoholic group, but with the acidic group, they could undergo a neutralizing reaction with other substances (acid and base exchange components to form salt and water). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction of alkene and alkyne with bromine water is an addition reaction at room temperature; organic matter containing an aldo group can undergo an oxido-reduction reaction with bromine water; a substitution reaction can occur with bromine water; a carbon-carbon double bond or carbon-carbon triple bond containing a carbon and a derivative of a carbon can react with bromine water (an addition reaction occurs to cause it to fade or to undergo an oxido-reduction reaction with a reducing substance). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chloration reaction of organic matter was the process of introducing a Cl-atom into the molecules of organic compounds. The common chloration reaction method was as follows: 1. Using SOCl2 or PCl/PClwas the most common method of chloridizing alcohol. The reaction mechanism using phosphorous acid as a source of chloridizing was similar. 2. Ph P/NCS (or (ClCl 3. Using MeLi then TsCi/LiCi, this method uses an alkyi lithium reagent as a base, which will form an oxygen negative ion, suitable for alcohol compounds with large steric hindrance. 4. Through TsCl-NaCl2, this method had an advantage for allylalcohol and had a good regional selection. 5. Relatively uncommon method: - Using the combination of DPS and DPS, it had a good selectively for allylalcohol and benzylalcohol, and other saturated alcohol was inactive under these conditions. - There was also a method similar to the Mitsuobu reaction, which would result in the reversal of the chirality center, which was applicable to both allylalcohol and saturated alcohol. In addition, the industry could also directly use Cl2 for the reaction. In organic compounds, there are generally two types of substitution and addition chloration. For example, the hydrogen in the molecular substitution of the chloridizing reagent could be replaced by the chloridizing reagent to form the chloridizing reagent. In the presence of an iron catalyst, the hydrogen in the chloridizing reagent could be replaced by the chloridizing reagent to form the chloridizing reagent. In addition, the chloridizing reagent could be used to form the chloridizing reagent, such as the chloridizing reagent, to form the chloridizing reagent. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
You're asking a little too suddenly." In simple terms, the mechanism of an organic reaction was to study how atoms, ions, or molecules interacted with each other when a chemical reaction occurred in an organic compound. For example, the oxidoreduction reaction involved the transfer of electrons. Which atoms gained electrons and which lost electrons was part of the reaction mechanism. There were also reactions such as acid and base reactions, and how hydrogen ions and hydrogen ions combined. These were also part of the research content of the reaction mechanism. However, this was just a very simple statement. In fact, there were many different types of reactions, and each had its own unique aspects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
At present, the research on the mechanism of organic reactions was based on the traditional types. There was no so-called "new model" that completely deviated from the traditional concept. The common types of organic reaction mechanisms still include the electropathic substitution reaction mechanism (For example, the electrophile in the substitution reaction of aromatic attacked the organic molecules rich in electrons), the mechanism of the nuclophile substitution reaction (In the Sn1 reaction, the reagent first dissociates into a carbon positive ion and a leaving group, and in the Sn2 reaction, the nuclophile attacks the electron deficient central atom, etc.), the electropathic addition reaction mechanism (Electrophiles attack the unsaturated bond, etc.), Nucleophile addition reaction mechanism (Nucleophile attacking the carbonyl-carbon atom, etc.), elimination reaction mechanism (E1 reaction first dissociates and then eliminate the hydrogen atom, E2 reaction base attacks the hydrogen atom while leaving the group, etc.), free radical reaction mechanism (the chain reaction is initiated by the free radical produced by the homolitic cleavage of the bond), reorganization reaction mechanism (the reorganization is initiated by different reasons under acidic, basic, and neutral conditions), and the peri-cycle reaction mechanism (the reaction is completed through the coordination of the ring-shaped transition state). With the continuous development of chemical research, the understanding of these reaction mechanisms continued to deepen. For example, the transfer of electrons in the reaction process, the structure and energy of the intermediate, and the reaction of the reaction became more detailed and accurate. However, it did not fundamentally change the framework of these basic organic reaction mechanisms. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photosynthesis referred to the biochemical process in which plants and algae used their own cells to convert carbon dioxide and water (bacteria were hydrogen sulphide and water) into organic matter and release oxygen (bacteria released hydrogen) under visible light. Plants use light energy to convert carbon dioxide and water into energy-storing organic matter and release oxygen. During this process, the plant absorbs visible light energy with the help of chlor other colors. Finally, the carbon dioxide is reduced, and oxygen is discharged. Then, sugar such as glucose is synthesized. During the light reaction stage of photosynthesis, for example, the black algae's plastids could decompose water to produce a large amount of oxygen and discharge it, while storing and transforming light energy, turning adenosine-bis-monophate into adenosine-bis-monophate (AAD into ATP-bis-monophate). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Additional reaction: - The addition reaction of ethene and Bromine: <<CH2 = CH2 + Br2> - The addition reaction of ethene and hydrogen bromidate was as follows: <CH2 = CH2> - Under certain conditions, addition reactions could also occur between ethene, hydrogen, and water. Since the chemical properties of ethyne (carbon-carbon triple bond) were similar to that of alkene (carbon-carbon double bond), similar addition reactions could also occur. - The aromatic ring can undergo an addition reaction with hydrogen (in the presence of a catalyst such as Ni). - Aldol groups can undergo a reduction reaction (addition reaction), such as: <anno data-annotation-id ="00000000 - 4c00 - 4c00 - 8c00 - 9c00 - 9c000b000000"> CH3CH20H </anno>. Substitution reaction: - The substitution reaction between methane and Cl2: CH4 + Cl2. - The substitution reaction of the aromatic ring: For example, the substitution reaction with the aromatic group using FeBr3 as a catalyst; the nitration reaction with the aromatic group using concentrated sulfuric acid under heating conditions (the hydrogen on the aromatic ring is replaced by the nitrogen group). - The substitution reaction of the halated carbon was as follows: <<CH3CH2Br2>+<NaBr2>>. - The substitution reaction of alcohol: <CH3CH20H>+<br>> longrightarrow <CH3CH2br>+<H2O>> - The ester's cleavage reaction (which can be seen as a substitution reaction):<CH3COOCH2CH3 + H2O> <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
