Question

In benzene $C-C$ bond length between all carbons are equal because of:

• A. tautomerism
• B. $s{p}^2$ hybridization
• C. isomerism
• D. resonance

Answer 1

Answer: (D)

resonance

In benzene CC bond length between all carbons are equal because of resonance. The pi electrons in benzene are delocalized over all the six carbon atoms. Hnce, all the carbon arbon bond orders in benzene are equal.
