Vedclass · Answer

(D) The stability of free radicals is determined by resonance,hyperconjugation,and inductive effects. $1$. $CH_2=CH-\dot{C}H_2$ is an allyl radical,which is resonance stabilized. $2$. $CH_2=\dot{C}H$ is a vinyl radical,which is highly unstable due to the $sp^2$ hybridized carbon atom. $3$. The radical in option $C$ is a cyclic allylic radical,which is resonance stabilized. $4$. The radical in option $D$ is a tertiary allylic radical,which is stabilized by both resonance and hyperconjugation (due to the methyl group and the ring structure). Comparing these,the tertiary allylic radical in option $D$ is the most stable due to the combined effects of resonance and increased hyperconjugation.

Which of the following is the most stable free radical?
