Answer 1

Vegetable Oil is a viscous liquid, and contains Unsaturated fatty acids, upon hydrogenation it is are converted to saturated fatty acids to form vanaspati ghee which is solid/semi solid in nature. For quick and easy hydrogenation, catalyst like Ni, Pt which are capable of adsorbing hydrogen are used.
