Question

The major products A and B in the following reactions are:

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

First reaction will generate a free radical which is stabilized by cyanide group.

The alkene undergo homolytic cleavage at the double bond and the terminal radical couple with [A] (secondary radical being more stable will not couple with [A]) forming product B (the secondary radical combines with hydrogen radical generated in the first step).
