Solution

The correct option is D
Nickel

Ethene reacts with hydrogen in the presence of a finely divided nickel catalyst at a temperature of about $300^{\circ} C$ to give ethane.

The hydrogenation or addition reaction holds true for any alkene in the presence of nickel catalyst. However, the hydrogenation reaction can also be carried out by using platinum or palladium as a catalyst.

Gaseous benzene reacts with hydrogen gas in presence of a nickel catalyst to form gaseous cyclohexane according to the reaction: $C_{6} H_{6} (g) + 3 H_{2} (g) \to C_{6} H_{12} (g) .$ A mixture of $C_{6} H_{6}$ and excess $H_{2}$ has a pressure of 60 mm of Hg in an unknown volume. After the gas has been passed over a nickel catalyst and all benzene converted to cyclohexane, the pressure of the gas was 30 mm of Hg at same volume and temperature. The fraction of $C_{6} H_{6}$ (by volume) present in the original volume is___.
