Which one of the following statements is not correct about benzene?
Correct answer: A. On hydrogenation, 208 KJ/mole is liberated.
- A. On hydrogenation, 208 KJ/mole is liberated.
- B. C-H bond length in benzene is 1.09 Å
- C. Molecular mass of benzene is 78.108
- D. Resonance energy of benzene 150.5 kcal/mole
Explanation
Benzene does not undergo typical hydrogenation reactions like alkenes do. It requires special conditions and a catalyst, and the process is less exothermic

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.
