The correct statement is

  1. A One mole each of benzene and hydrogen when reacted gives \( 1 / 3 \) mole of cyclohexane
    and \( 2 / 3 \) mole unreacted hydrogen.
  2. B It is easier to hydrogenate benzene when compared to cyclohexene.
  3. C Cyclohexadiene and cyclohexene cannot be isolated with ease during controlled
    hydrogenation of benzene.
  4. D Hydrogenation of benzene to cyclohexane is an endothermic process.
Verified Solution

Answer & Solution

Correct Answer

(C) Cyclohexadiene and cyclohexene cannot be isolated with ease during controlled
hydrogenation of benzene.

Step-by-step Solution

Detailed explanation

During the hydrogenation of benzene only cyclohexane can be isolated.

Benzene
Cyclohexane
Therefore, cyclohexadiene and cyclohexene cannot be isolated with ease during controlled hydrogenation of benzene.
