If both the Assertion and Reason are incorrect.

Vedclass · Answer

(D) The Assertion is incorrect because benzene does not exhibit two different bond lengths; all $C-C$ bonds in benzene are equivalent due to resonance.The Reason is correct because the actual structure of benzene is a resonance hybrid of the two Kekulé structures shown.Benzene has a uniform $C-C$ bond distance of $139 \ pm$, which is an intermediate value between the $C-C$ single bond $(154 \ pm)$ and $C=C$ double bond $(134 \ pm)$ lengths.

Assertion : Benzene exhibits two different bond lengths, due to $C-C$ single and $C=C$ double bonds.
Reason : Actual structure of benzene is a hybrid of the following two structures.
