Among the following, which one has the weakest carbon-halogen bond?
1 Benzyl bromide
2 Bromobenzene
3 Vinyl bromide
4 Benzyl chloride
Explanation:
\({\rm{C}} - {\rm{X}}\) 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 stabilised by resonance. Further, \(\mathrm{C}-\mathrm{Br}\) bond is weaker than \(\mathrm{C}-\mathrm{Cl}\) bond due to larger size of \(-\mathrm{Br}\). Therefore, \(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{CH}_{2} \mathrm{Br}\) has the weakest \({\rm{C}} - {\rm{X}}\) bond.

For the compounds \(\mathrm{CH}_{3} \mathrm{Cl}, \mathrm{CH}_{3} \mathrm{Br}, \mathrm{CH}_{3} \mathrm{I}\) and \(\mathrm{CH}_{3} \mathrm{~F}\), the correct order of increasing \(\mathrm{C}\)-halogen bond length is
The correct order of increasing bond length is \(\mathrm{CH}_{3} \mathrm{~F} < \mathrm{CH}_{3} \mathrm{Cl} < \mathrm{CH}_{3} \mathrm{Br} < \mathrm{CH}_{3}\) I Bond length increases with increase in size of halogen.
