Question

Hydrogenation involve the saturation of which type of linkage?

(a) Carbon-carbon

(b) Carboxyl group

(c) Hydroxyl group

(d) All of the mentioned

This question was addressed to me by my college professor while I was bunking the class.

My enquiry is from Hydrogenation in chapter Hydrogenation of Unit Processes

Answer 1

Right option is (d) All of the mentioned

Easiest explanation: Hydrogenation may involve the saturation of a carbon-to-carbon linkage or the reduction of carbonyl or carboxyl or hydroxyl groups and may even involve the breaking of carbon-to-carbon linkages, as in the hydrogenation of coals and mineral oils.
