Toluene

Vedclass · Answer

(A) The bond dissociation energy of a $C-H$ bond depends on the stability of the radical formed after the homolytic cleavage of the bond.In toluene $(C_6H_5CH_3)$,the removal of a hydrogen atom from the methyl group results in the formation of a benzyl radical $(C_6H_5CH_2^{\bullet})$.This benzyl radical is highly stabilized by resonance with the benzene ring,as shown in the provided resonance structures.Since the resulting radical is very stable,the energy required to break the $C-H$ bond in the methyl group of toluene is the lowest among the given options.

$I. -OH$	$II. -CN$
$III. -CO_2H$	$IV. -OCH_3$
$V. -NHCOCH_3$	$VI. -CHO$

Which of the following compounds possesses the $C-H$ bond with the lowest bond dissociation energy?
