The color reaction of iron, organic or mineral reaction
The color reaction of iron could be either an organic reaction or an organic reaction. For example, thiodic cyanogen ion (SCN -) could combine with iron ions to form a blood-red iron thiodic cyanide complex. This was an organic color reaction. The principle was to use the strong coordination of thiodic cyanogen ions to coordinate with the iron ions to form a complex. In terms of organic reactions, for example, the reaction of the alcoholic group (directly attached to the aromatic ring) with iron ions to form a purple (Fe6H5O)6)3+ complex was an organic color reaction. Here, the strong coordination of the aromatic group was used to form a complex with iron ions. Read more exciting novels for free
The reaction of iron trioxide-hy-odic acid with organic and organic substances
Iron dioxide (Fe2 O2) reacted with hy odic acid (Hi). In terms of organic substances, the reagents were iron dioxide and hy odic acid. The reaction equation was: Fe2 O2 + 6Hi = 2FeI <2>+ I <2>+3H <2> O. The iron dioxide (FeI <2>) and water (H <2> O) in the product were both organic substances. Iodine (I <2>) was a simple substance, which was also an organic substance. This reaction did not involve organic matter. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
organic chloridizing reaction
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>
Reaction Formula of Substitution Reaction for the addition reaction of organic substances
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>
Incomplete reaction of organic matter
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>
New organic reaction mechanism
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>
What is the mechanism of the organic reaction?
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>
What are the conditions for the color reaction of iron chloride?
Most of the compounds with the structure of a hydrogen radical and an sp2 hybrid carbon atom (that is, the carbon atom on the carbon-carbon double bond) could undergo a color reaction with the water solution of FeCl3. The alcoholic group was directly connected to the aromatic ring, which was equivalent to a dilute alcohol structure, so there was also this reaction. The colors of different compounds were different. For example, the colors of the compounds of the two compounds were blue-purple, the colors of the compounds of the two compounds were green, and the colors of the compounds of the two compounds were blue. The reaction mechanism was generally believed to be the formation of a complex and color development. The iron chloride-like reaction was widely used to identify substances with enol structures. Sp2 hybrids were formed by one s orbital and two of the three p orbitals on the same layer. They were mostly used to form two single bonds and one double bond, which formed alkene, aldo, keto, and acyl in organic matter. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction of the name of the organic zincate reagent
The name of the reaction related to the organic zincate reagent was the Reformasky reaction (Reformaskii reaction), which was a reaction in which an organic zincate reagent prepared from an alpha halo ester and a titanium powder carried out a nuclopathic addition reaction on a carbonyl-based compound (aldo, keto, ester) to form a beta-hy-droxy ester. There was also the Fukuyama (Fukuyama) couple reaction, which referred to the reaction of an organic zincate compound and a thionate ester to form a keto under a palladium-based catalyst. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the relationship between reduction reaction and addition reaction in organic chemistry?
The reduction reaction and addition reaction in organic chemistry were interlinked. The reduction reaction mainly referred to the deoxidization or dehydration reaction of organic compounds. The addition reaction was a reaction in which the saturated carbon atoms in the organic molecules directly combined with other atoms or atomic groups to form new substances. In organic chemistry, some reactions were both reduction reactions and addition reactions, such as the dehydration reaction. There were also many addition reactions that were not hydrogen addition, such as the hydrating reaction (the radical addition) or the addition with a halo. These were all addition non-reduction reactions. There was also the deoxidization reaction of organic matter, which was a reduction reaction but not an addition reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What color is the reaction of the reaction between the two?
There was no obvious phenomenon when a small amount of Bromine water was dripped into the solution of the sulfuric acid. When a slight excess of Bromine water was dripped into the solution, white precipitations would appear. When the sulfuric acid reacted with the concentrated Bromine water to form white precipitations, the concentrated Bromine water was added, and the white precipitations would turn into yellow precipitations. Dropping a small amount of the solution of the sulfuric acid into the concentrated Bromine water, a white deposit immediately appeared, and then turned into a yellow deposit. This was because the white deposit of tribrom-phenol was formed after the addition of the sulfuric acid into the concentrated Bromine water. When the amount of Bromine water was excessive, the Bromine would dissolve in the tribrom-phenol, and the yellow deposit would appear. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
