Compare stability of the following free radicals.

Question

Compare stability of the following free radicals. (A) II > I > III > IV (B) II > I > IV > III (C) I > II > III > IV (D) IV > III > I > II

Tardigrade Admin · Accepted Answer

Allyl and benzyl radicals are stabilized by resonance, tertiary and secondary radicals are possibly stabilized by hyperconjugation but tertiary is more stable than secondary. Thus the correct order of stability of given free radicals is- II > I > IV > III
