Question

X-ray diffraction proves all carbon-carbon bonds in benzene are identical. What is the measured length of the completely delocalized $C-C$ bonds in the benzene ring?

Prashant Kotian · Accepted Answer

Correct answer: A. The extensive resonance delocalization of electrons in benzene results in a partial double-bond character for all C-C bonds, averaging their length to , intermediate between a single and double bond.
