The correct statement is

Options

  1. AOne mole each of benzene and hydrogen when reacted gives ( 1 / 3 ) mole of cyclohexane and ( 2 / 3 ) mole unre
  2. BIt is easier to hydrogenate benzene when compared to cyclohexene.
  3. CCyclohexadiene and cyclohexene cannot be isolated with ease during controlled hydrogenation of benzene.
  4. DHydrogenation of benzene to cyclohexane is an endothermic process.

Correct answer

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

Step-by-step solution

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.
