Which reaction is faster, the reaction between the halo and the alkene?The addition reaction between alkene and halo was an electropathic addition. The more substituted groups on the double bond, the higher the electron cloud density, and the faster the addition reaction with the halo. However, if the substituted group was too large, there would be a steric hindrance effect. The order of the reaction activity of the halo is: F2 >> Cl2 >> Br2 >> I2. However, F2 has a fierce reaction with alkene, releasing a lot of heat, which will decompose alkene. I2 generally does not have an ion reaction with alkene.

Cyclopropan plus hydrogen halo reactionCyclopropan was prone to an addition reaction with hydrogen Halide at room temperature. Cyclopropan was more active than ordinary cycloalkyls. Due to its carbon ring structure (small ring compounds were less stable), it was easy to open the ring and undergo an addition reaction to become an open chain carbon. This reaction was a typical reaction of cyclopropan as a small ring compound, and it was a manifestation of its active chemical properties.

Does the elimination reaction require a halo atom?The elimination reaction didn't necessarily require the presence of a halo atom. The elimination reaction of the substituted alcohol required the presence of a hydrogen atom. When the substituted alcohol was heated in an alcoholic solution of the solution However, alcohol could also undergo an elimination reaction. Alcohol could form alkene under the condition of sulfuric acid. In this case, there were no halo atoms involved. In addition, alcohol with only one carbon could not undergo an elimination reaction, and alcohol with a halo atom or a carbon without a hydrogen atom attached to a hydrogen atom could not undergo an elimination reaction.

Reactivity of the addition reaction between a halo and an alkeneThe order of the reaction activity of the addition of halo and alkene was: F <2>> Cl2> Br2> I2 <2>. Fluor was too active, and the addition reaction with alkene was violent and accompanied by substitution reaction, resulting in many by-products. Iodine was not active enough, so the addition was difficult and the reaction was irreversible.

What is the reason for the slow reaction in League of Legends?The reason why League of Legends reacted too slowly was as follows:
** 1. Equipment related reasons **
1. ** The computer configuration is too low **
- If the hardware configuration of the computer couldn't meet the requirements of the game, it would cause the overall operation of the game to be uneven, which would affect the reaction time. For example, if the graphics card configuration was low, there would be a delay when processing the rendering of the game screen, causing the game screen that the player saw to lag behind the actual operation, affecting the timing of the movement. Generally speaking, if the memory was small, the game might be stuck due to insufficient memory, especially in complex game scenes, such as large-scale team battles, the reaction time would be very slow.
2. ** Driving problem **
- The graphics card driver is not installed or the installed driver version is incompatible, which will affect the performance of the graphics card. For example, if the graphics card driver was not installed correctly after the system was completed, or if the driver settings were incorrect, it might cause the game screen to be stuck and the positioning response to be delayed. In addition, if you use the core graphics card to play games, and the performance of the core graphics card is limited, it will also cause this situation.
3. ** Mouse and keyboard issues **
- The sensitivity setting of the mouse might not be appropriate. If the mouse's sensitivity was too low, the mouse would move very slowly to the target position when it needed to move quickly, which would affect the reaction speed. On the keyboard, if there was a situation where the keys collided or the keys were not sensitive, for example, when the direction key was pressed to move, the keyboard could not respond to the operation in time, which would also cause the movement to be slow.
** 2. In-game settings related reasons **
1. ** Picture setting is too high **
- The game's graphics settings, such as resolution and special effects, would increase the burden on the graphics card and CPU. For example, setting the resolution to a very high value and turning on high quality and special effects at the same time would require a lot of computing resources to process the game screen, which might cause the game to be slow and slow when moving.
2. ** Unnecessary functions are not turned off **
- Some of the functions in the game, such as background music when choosing a hero, the recording function, etc., might take up a certain amount of system resources if they were not turned off. Especially the recording function. During the recording process, data would be continuously written in, which might cause the game's running speed to decrease, affecting the smoothness of the movement and reaction speed.
** 3. Internet-related reasons **
1. ** Network delay or instability **
- The network delay was too high. Even if the delay value was not high, the actual network was unstable, and the transmission of game data would be affected. In this case, the player's operation instructions could not be transmitted to the game server in time, and the game screen fed back by the server could not reach the player in time, resulting in a slow reaction time. For example, when the network was heavily occupied by other applications, such a situation could occur in League of Legends.

2017 League of Legends Opening Ceremony Foreigners 'ReactionIn the opening ceremony of the 2017 League of Legends S7 final, VR/AR technology was used in the part where the ancient dragon invaded the Bird's Nest. The reactions of the foreign audience when watching the live broadcast were mainly shock. Most of the comments on the bullet screen during the live broadcast were emojis or "WTF!" After the incident, many players discussed this matter on the foreign forums. The official members of the Fist also appeared in the post and expressed some opinions. For example, a staff member explained that the camera was man-made, and it was very difficult to perfectly integrate the camera with the Ancient Dragon at first. He also mentioned that the audience could only see the dragon through the big screen, and they would think of a way to break through this restriction.

Analysis of the calculation problem of the substitution reaction between halo and alkyls1. **根据反应关系确定烷烃分子式**
- 在烷烃与卤素单质的取代反应中,有这样的关系:当烷烃分子中的1mol氢原子被取代时,就需要有1mol氯气(或其他卤素单质,反应原理相同)参加反应,同时生成1mol氯化氢(或相应卤化氢)。例如,1mol某烷烃可与8molCl₂完全取代,这意味着该烷烃分子中含有8mol氢原子。设烷烃的分子式为CₙH₂ₙ + ₂,根据氢原子数为8,可得2n+2 = 8,解得n = 3,所以该烷烃的分子式为C₃H₈。
2. **关于活性比与反应量计算**
- 以丙烷与Cl₂的一氯取代反应为例,已知两侧甲基氢原子与中间亚甲基氢原子的活性之比为1:3。如果有一定量的丙烷与氯气反应,假设反应的丙烷为1mol,丙烷中两侧甲基氢原子总数为6个,中间亚甲基氢原子数为2个。根据活性比,如果反应消耗的氢气总量为xmol,那么两侧甲基氢原子反应量为\(\frac{1}{4}x\)mol,中间亚甲基氢原子反应量为\(\frac{3}{4}x\)mol。
- 例如,若反应后生成的一氯丙烷总量为0.5mol,设两侧甲基上发生取代反应生成的一氯丙烷为ymol,则中间亚甲基上发生取代反应生成的一氯丙烷为(0.5 - y)mol。根据活性比\(\frac{y}{6}:\frac{0.5 - y}{2}=1:3\),通过这个比例关系可以计算出y的值,从而确定在不同位置发生取代反应的产物量。
3. **根据能量变化图计算反应趋势相关量**
- 对于丙烷与溴原子的反应,如反应①CH₃CH₂CH₃(g)+Br·(g)→CH₃CH₂CH₂·(g)+HBr(g)和反应②CH₃CH₂CH₃(g)+Br·(g)→(CH₃)₂CH·(g)+HBr(g),从能量变化关系图可以推断反应的趋势。如果知道反应的活化能等能量数据,可以计算反应的速率常数等与反应速率相关的量。例如,根据阿仑尼乌斯公式\(k = A\times e^{-\frac{Ea}{RT}}\)(其中k为反应速率常数,A为指前因子,Ea为活化能,R为理想气体常数,T为温度),若已知两个反应的活化能Ea₁和Ea₂,在相同温度T下,可以比较两个反应的速率常数\(k₁\)和\(k₂\)的大小,进而确定反应进行的快慢程度。如果给出反应达到平衡时的一些条件,如平衡常数K,也可以通过平衡常数表达式计算各物质的平衡浓度等相关量。例如,对于反应①,若平衡常数\(K=\frac{[CH₃CH₂CH₂·][HBr]}{[CH₃CH₂CH₃][Br·]}\),已知平衡时某些物质的浓度或分压,就可以计算出其他物质的浓度或分压。

What is the principle of the reaction between the elemental halo and the concentrated base?The principle of the reaction between the elemental halo and the concentrated base could be seen as the elemental halo reacting with water first, and the resulting product (acid) reacting with the base. For example, the reaction of Cl2, Br2, and I2 with alkalium could be regarded as reacting with water to form the corresponding hydrogen halic acid and hypohalic acid, and then these acid reacted with alkalium to form a haiide, hypohalic acid salt, and water. When F <2> reacted with alkalium, 2F <2>+2NaF + OF <2>+ H <2> O, and F <2> reacted with water to form sulfuric acid and oxygen, which then reacted with alkalium. However, I <2> reacted with an alkali-based solution at room temperature to form iodate, which was a special case. Cl2 <2> and Br2 <2> reacted with an alkali-based solution at room temperature to form hypohalite. Only when heated and reacted with a concentrated alkali-based solution could the hypohalite be formed. F <2> could not obtain "fluorite" at any temperature with an alkali-based solution.
