Question

Why all the C-C bond length in benzene are equal

Answer 1

Answer: Due to resonance

Explanation:

As in structure of benzene there are both single and double C-C bonds.

Thus, π electron is deloclised equally in all CC bonds.

So,,

In resonance hybrid there are mixture of single and double bonds so, all the

C-Cbonds in benzene have average length of C-Csingle and double bonds.

Hope it helps.

Answer 2

Answer:

In benzene CC bond length b/w all carbons are equal because of resonance. The pi electron in benzene are delocalized over all the 6 carbon atoms. Hence all the C-C orders in benzene are equal.
