Type: MCQ-numerical-Medium-Class 11
Given the reaction CH3–C≡C–H + 2H2 → CH3–CH2–CH3 using Pt/Pd/Ni as a catalyst, calculate the number of moles of hydrogen gas required to completely hydrogenate 1 mole of propyne to propane.
A
2 moles
B
1 mole
C
3 moles
D
0.5 moles
Correct Answer
Option A
Detailed Explanation
From the given reaction, CH3–C≡C–H (propyne) reacts with 2 moles of H2 to form CH3–CH2–CH3 (propane), so 2 moles of H2 are required for hydrogenation of 1 mole of propyne.
