MCQ
All bonds in benzene are equal due to
- ATautomerism
- BInductive effect
- ✓Resonance
- DIsomerism
✓
Answer
Correct option: C.
Resonance
c
(c) All the bonds $(C - C)$ are equal in benzene
(c) All the bonds $(C - C)$ are equal in benzene
The C-C bond length is $1.39\,\mathop A\limits^o $ which is in between $C-C$ bond $(1.34\, \mathop A\limits^o )$ and $C-C$ $(1.34\, \mathop A\limits^o )$.
