Consider the following compounds: Hyperconjugation occurs in

A

III only

B

I and II

C

I only

D

II only

Text Solution

Verified by Experts

The correct Answer is:
A

Hyperconjugation in free radicals occurs only when the `alpha`-carbon to the carbon atom carrying the odd electron has a hydrogen atom, ie,
Radicals (I and II) do not have hydrogen/s on the `alpha`-carbon/s and hence do not show hyperconjugation.
