Question

Consider the following compound (X):
 
The most stable and least stable carbon radicals, respectively, produced by homolytic cleavage of corresponding C - H bond are:

• A. I, IV
• B. III, II
• C. II, IV
• D. I, III

Hint:

Radical stability increases with the number of alkyl groups attached to the carbon carrying the radical. The more alkyl groups, the more stable the radical.

Answer 1

The Correct Option is D

The most stable carbon radical due to stabilization by adjacent alkyl groups is III, while the least stable radical is I as it lacks such stabilization.
