Question:
Identify the catalyst used for hydrogenation of oil.
Identify the catalyst used for hydrogenation of oil.
Show Hint
Finely divided nickel (Raney Ni) is the catalyst for hydrogenation of oils to give vanaspati ghee.
Updated On: Nov 12, 2026
- \(\text{V}_{2}\text{O}_{5}\)
- \(\text{Fe}\)
- Raney Ni
- \(\text{MnO}_{2}\)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Hydrogenation of unsaturated oils adds hydrogen across the double bonds to make saturated fats.
Step 2: Catalysts in industry
\(\text{V}_{2}\text{O}_{5}\) is used in the contact process.
Fe is used in the Haber process.
\(\text{MnO}_{2}\) is used in the decomposition of \(\text{KClO}_{3}\).
Step 3: Compare the options
Hydrogenation of oil uses finely divided nickel, Raney Ni, which is option (C).
Final Answer:
Raney nickel is the catalyst. \[ \boxed{\text{(C) }\text{Raney Ni}} \]
