Question

With the help of an example, explain the process of hydrogenation. Mention the essential conditions for the reaction and state the change in physical property with the formation of the product.(Delhi - 2015)

Answer 1

Explanation:

hydrogenation si the adding h2 either to alkene or alkyne......there should be at least 200 degree Celsius temperature and nickel should be used as catylyst

Answer 2

Answer:

Explanation is given below

Explanation:

Adding of hydrogen to an unsaturated compound, the process is called hydrogenation.

Example:

Ethene gives ethane as a product on hydrogenation.

Conditions for hydrogenation:

(1) Unsaturated compound i.e., unsaturated hydrocarbon should be present.

(2) Presence of a catalyst such as finely divided palladium or nickle.

During hydrogenation of vegetable oils, liquid unsaturated fatty acids are converted into solid saturated fatty acids.
