The carbon-carbon bond distance in benzene:
Correct answer: D. 1.39oA
- A. 1.54oA
- B. 1.34oA
- C. 1.2oA
- D. 1.39oA
Explanation
C−C bond length in benzene is 1.39 ˚A.The bond length C-C ( single bond as in ethane ) is 1.54 Å and C=C ( double bond as in ethene is 1.33Å. The carbonate carbon bond length in benzene has been found to be 1.39Å which lies between single and double bond length value.

About Benzene and Aromatic Compounds
Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
