A) Benzyl bromide
B) Bromobenzene
C) Vinyl bromide
D) Benzyl chloride
Correct Answer: A
Solution :
C?X bond in benzyl bromide is much weaker than in vinyl bromide and bromobenzene since the benzyl cation left after the removal of the bromide ion is stabilized by resonance. Further, C?Br is weaker than C?Cl bond. Therefore, \[{{\text{C}}_{\text{6}}}{{\text{H}}_{\text{5}}}\text{C}{{\text{H}}_{\text{2}}}\text{Br}\]has the weakest C?X bond.
