Question

The reaction of N-bromosuccinimide (NBS) with cyclohexene in the presence of a
radical initiator leads to which one of the following products ?
(B) 1,2-Dibromocyclohexane​

Answer 1

Answer:

N-Bromosuccinamide reacts with cyclohexene in the presence of a radical initiator and gives 1,2-bromocyclohexene

Explanation:

In this radical mechanism reaction N - Bromosuccinamide will provide the bromine radical and bromine radical attack with the cyclohexene to make brominium ion as an intermediate again another N - Bromosuccinamide will provide bromine radical and attack at brominium ion to make 1,2-bromocyclohexene.

Therefore,

N-Bromosuccinamide reacts with cyclohexene in the presence of a radical initiator to give 1,2-bromocyclohexene as a product
