The additions of HCl to an alkene proceeds in two steps. The first step is the attack of `H^(+)` ion to portion which can be shown as

A

B

C

D

All of these are possible

Text Solution

Verified by Experts

The correct Answer is:
B

Step I `pi` bonds creates an electron cloud, Electrophile `(H^(+)C)` from `H - Cl` attacks the electro cloud, delocalising the electrons. And, a carbocation is formed

Step II The chloride anion attacks the carbocation
