(c) Sulphur

(d) Nitrogen

I had been asked this question by my school teacher while I was bunking the class.

Question is from Equipments and Processes topic in section Amination by Reduction of Unit Processes

Answer 1

Correct option is (a) Hydrogen

The best I can explain: Hydrogen is manufactured in large quantities for a variety of uses in addition to amination. It is used for hardening of oils and fats in the food industry, for the production of ammonia and methanol, for improving the octane number of gasoline, for the production of alcohols by the Oxo process and by reduction of fats and fatty acids, for the production of synthetic gasoline and lubricating oils, for the desulfurization of hydrocarbon materials, for providing reducing atmospheres in the metalworking industry, and for many other purposes in industrial synthetic organic chemistry.
