Question

Name the functional group of organic compounds that can be hydrogenated. With the help of suitable examples explain the process of hydrogenation mentioning the conditions of the product. Name any one natural source of organic compounds that are hydrogenated.

Answer 1

The functional group of organic compounds that can be hydrogenated are ‘alkenes’ and ‘alkynes’ Hydrogen can be added to unsaturated hydrocarbons in the presence of nickel to yield saturated hydrocarbons. In this reaction, nickel acts as a catalyst. On hydrogenation, the unsaturated fatty acids which are liquid at room temperature become saturated and change to solid. A natural source of organic compound that is hydrogenated is vegetable oil.
