    Among the following which one has weakest carbon-halogen bond?

    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,\[{{C}_{6}}{{H}_{5}}C{{H}_{2}}Br\]has the weakest\[C-X\]bond.
