Question

Draw the mechanism for the reaction of cyclohexene with HCl

Short answer

Cyclohexene is a hydrocarbon that is produced by hydrogenating benzene and is utilised as an industrial intermediate chemical in the production of tetrahydro benzoic acid, adipic acid, and malic acid, as well as in oil extraction.

HCl is a hydrogen halide, while cyclohexene is an alkene. With the addition of an electrophilic reagent, hydrogen halides react with alkene to form alkyl halides.

Step-by-step solution

Definition of cyclohexene-

Cyclohexene is a hydrocarbon that is produced by hydrogenating benzene and is utilised as an industrial intermediate chemical in the production of tetrahydro benzoic acid, adipic acid, and malic acid, as well as in oil extraction.

HCl is a hydrogen halide, while cyclohexene is an alkene. With the addition of an electrophilic reagent, hydrogen halides react with alkene to form alkyl halides.

Mechanism for the reaction of cyclohexene with HCl-

The following is the electrophilic addition reaction mechanism for the reaction of cyclohexene with HCl-

Here, cyclohexene has a sp² carbon, and an electrophile (H⁺) is added to the sp² carbon, forming a carbocation intermediate, which reacts quickly with the nucleophile (Cl^-) to form an alkyl halide.
