Vedclass · Answer

(C) The stability of free radicals is determined by resonance,hyperconjugation,and inductive effects.$1$. Radical $2$ is benzylic,which is highly stabilized by resonance with the phenyl $(Ph)$ group.$2$. Radical $4$ is allylic,which is stabilized by resonance with the adjacent double bond.$3$. Radical $3$ is a secondary $(2^{\circ})$ alkyl radical with $4$ $\alpha$-hydrogens,providing hyperconjugative stabilization.$4$. Radical $1$ is a primary $(1^{\circ})$ alkyl radical with only $1$ $\alpha$-hydrogen,making it the least stable.Thus,the order of increasing stability is $1 < 3 < 4 < 2$.

Rank the following radicals in order of increasing stability (least $ < < < $ most).
