The C-Br bond in bromobenzene as compared with C-Br bond in ethyl bromide is
Answer & explanation
Correct answer: option 3
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.
