Question

1.Ethene undergoes addition reaction with hydrogen in the presence of catalyst like Ni to produce ethane.

This reaction called as catalytic hydrogenation can be used for the conversion of double bonds in big molecules like those of oils into single bonds, without affecting the ester linkages and produces fully saturated compounds known as fats.

(a)Given below is the structure of oil which contains double bonds. Write the product when it is reacted with excess of hydrogen in the presence of Ni.

Oils are liquids at room temperature while fats are semi-solids. Which has a low melting point, oil or fat?

Answer 1

Dear Student,

Addition of hydrogen takes place across the double bonds and the given compound will be converted into saturated one.
