Question

The gas used in the hydrogenation of oils in presence of nickel as a catalyst to give vanaspathi is _______.

• A. $O_2$
• B. $N_2$
• C. $H_2$
• D. $C{l}_2$

Answer 1

Answer: (C)

$H_2$

Hydrogenation is the addition of hydrogen. So, hydrogen gas is used in the hydrogenation of oils in the presence of Ni catalyst to give vanaspathi. By hydrogenation of oil, the unsaturated oils are converted to saturated vanaspathi. Apart from that hydrogenation improves taste, odour, and preservation.
