The C-Br bond in bromobenzene as compared with C-Br bond in ethyl bromide is

Shorter and stronger

The correct answer is Option (3) → Shorter and stronger

In bromobenzene, the C–Br bond has partial double bond character due to resonance between the bromine lone pair and the benzene ring. This makes the bond:

• Shorter than a normal C–Br single bond
• Stronger than the C–Br bond in alkyl halides

In ethyl bromide, the C–Br bond is a normal single (σ) bond, so it is longer and weaker.
