Which gas is used in the manufacture of Vanaspati Ghee?
Show Hint
Hydrogenation = Addition of Hydrogen + Nickel catalyst + Liquid Oil $\rightarrow$ Solid Fat.
Updated On: May 5, 2026
- Oxygen
- Nitrogen
- Hydrogen
- Carbon dioxide
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Vegetable oils are unsaturated fats (containing double bonds). To make them solid (like ghee), they must undergo a chemical process called hydrogenation.
Step 2: Meaning
Hydrogenation involves the addition of hydrogen atoms to the double bonds of the oil molecules in the presence of a catalyst like Nickel.
Step 3: Analysis
Oxygen would cause rancidity, Nitrogen is inert, and $CO_{2}$ does not react with oils. Hydrogen gas is the only one that chemically transforms liquid oil into solid fat.
Step 4: Conclusion
Therefore, Hydrogen gas is essential for the production of Vanaspati Ghee. Final Answer: (C)
