Vedclass · Answer

(D) To determine the stability of free radicals,we compare the factors affecting their stability such as resonance,hyperconjugation,and inductive effects.In option $B$,the radical on the right is a tertiary alkyl radical,which is stabilized by hyperconjugation from $9$ $\alpha$-hydrogens,whereas the radical on the left is a secondary alkyl radical,which is stabilized by hyperconjugation from $4$ $\alpha$-hydrogens. Thus,the tertiary radical $(B)$ is more stable than the secondary radical $(A)$.In option $C$,the radical on the right is a primary alkyl radical,while the radical on the left is a cyclopropyl radical. The cyclopropyl radical is less stable due to high angle strain.In option $D$,$Ph_{3}\dot{C}$ is more stable than $(CH_{3})_{3}\dot{C}$ because resonance stabilisation in $Ph_{3}\dot{C}$ is much more effective than the hyperconjugation in $(CH_{3})_{3}\dot{C}$.Therefore,in pair $D$,$A$ is more stable than $B$.

In which of the following pairs is $A$ more stable than $B$?
$A$ $B$
