Question

With the help of a suitable example explain the process of hydrogenation reaction mentioning condition of addition reaction and change in

Answer 1

Hrdrogenation is a process to obtain saturated hydrocarbons from unsaturated hydrocarbons.

See a common example :-

The unsaturated hydrocarbon ethene is reduced to ethane.

The conditions require pressure (different for different reactions) and catalyst such as Ni, Pd, Pt...

The Physical properties might change as follows :-

(i) Unsaturated hydrocarbons are mainly insoluble in water but saturated are soluble. Therefore the insoluble becomes soluble .

(ii) The boiling point and freezing point changes as accordance to the compounds.
