X-ray diffraction proves all carbon-carbon bonds in benzene are identical. What is the measured leng — Hydrocarbons Chemistry Question

💡 Solution & Explanation

The extensive resonance delocalization of $\pi$ electrons in benzene results in a partial double-bond character for all C-C bonds, averaging their length to $1.39 \text{ \AA}$, intermediate between a single ($1.54$) and double ($1.34$) bond.
