Multiple choice

Which of the following statements is/are false? A. The resonance energy of benzene is higher than its heat of hydrogenation. B. The greater stability of trans-but-2-ene can be explained on the basis of hyperconjugation effect. C. Dichlorocarbene (:CCl2) is a nucleophile.

  1. Only A

  2. Only B

  3. Only C

  4. Both A and C

  5. A, B and C

E Correct answer
Explanation

This option is correct,  because the resonance energy of benzene is lower (151 kJ/mole) than its heat of hydrogenation (208 kJ/mole), the greater stability of trans-but-2-ene can be explained on the basis of steric hindrance and Dichlorocarbene (:CCl2) is an electrophile.
