Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Transition metals with high surface areas are used as catalysts for adding hydrogen to unsaturated bonds.
Step 2: Meaning
Platinum (Pt), Palladium (Pd), and Nickel (Ni) are standard hydrogenation catalysts.
Step 3: Analysis
Iron (Fe) is typically used as a catalyst in the Haber process (ammonia synthesis) rather than simple alkene hydrogenation.
Step 4: Conclusion
Pt, Ni, and Pd are the suitable catalysts. Final Answer: (C)
