Vedclass · Answer

(A) The bond dissociation energy required to form the benzyl radical $(C_6H_5CH_2^{\bullet})$ from toluene $(C_6H_5CH_3)$ is less than that required to form the methyl radical $(CH_3^{\bullet})$ from methane $(CH_4)$.This is because the benzyl radical is stabilized by resonance with the benzene ring,which lowers the energy of the radical intermediate.In contrast,the methyl radical lacks such resonance stabilization.

The bond dissociation energy needed to form the benzyl radical from toluene is $.....$ than the formation of the methyl radical from methane.
