What is the value of C-C bond length in benzene?
Correct answer: D. 139.7 pm
- A. 154.0 pm
- B. 120.0 pm
- C. 134.0 pm
- D. 139.7 pm
Explanation
The correct answer is 139.7 pm. The typical C-C bond length in benzene is around 140 pm. This value may vary slightly depending on experimental conditions. The unique structure of benzene with its alternating single and double bonds contributes to its stability and aromaticity. Options A, B, and C are incorrect because they provide values that are not in line with the typical C-C bond length in benzene.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
