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.
