Question

What is the product when an unsymmetrical alkene undergoes anti‑Markovnikov addition of HBr in the presence of peroxides?
Options
A The same as the Markovnikov product
B The bromine adds to the less substituted carbon
Correct Answer
C The product is always a tertiary alkyl bromide
D No reaction occurs
Correct Answer

Option B is the correct answer.

Detailed Explanation

Peroxide effect (free‑radical addition) gives anti‑Markovnikov orientation: Br adds to the less substituted carbon.

Hint

Radical mechanism reverses regiochemistry.
