Which of the following catalytic systems is used for the reduction of unsaturated hydrocarbon to saturated hydrocarbon?
General KnowledgeChemistry
- ACopper and H2
- BIron and H2
- CZinc and H2
- DNickel and H2
Explanation
The reduction (hydrogenation) of unsaturated hydrocarbons to saturated hydrocarbons is classically carried out with hydrogen gas in the presence of a nickel catalyst (e.g. Raney nickel) under heat and pressure. Copper, iron and zinc with hydrogen are not the standard catalytic systems for this hydrogenation. The answer is (D).
