Question

A tertiary butyl free radical is more stable than a secondary butyl free radical because of which of the following?

• A. $+R\text{effect of}–C{H}_3\text{groups}$
• B. $-R\text{effect of}–C{H}_3\text{groups}$
• C. $\text{Hyperconjugation}$
• D. $-I\text{effect of}–C{H}_3\text{groups}$

Answer 1

The correct option is C $\text{Hyperconjugation}$


is very stable due to hyperconjugation effect. More the number of $\alpha -H$ atoms more will be the hyperconjugation effect, hence more will be stability.
