X-ray diffraction analysis of benzene reveals that all six carbon-carbon bonds are identical. What i — Aromatic Hydrocarbons Chemistry Question

💡 Solution & Explanation

The C-C bond length in benzene is 1.39 Angstroms, which is exactly intermediate between a standard C-C single bond (1.54 A) and a standard C=C double bond (1.34 A), proving complete pi-electron delocalization.
