Calculate the number of moles of dihydrogen required to completely hydrogenate one mole of propyne to propane using a nickel catalyst.
A
2 moles
B
1 mole
C
3 moles
D
0.5 moles
Correct Answer
Option A
Detailed Explanation
Propyne (CH3-C≡C-H) contains a triple bond and requires two moles of dihydrogen (H2) to be fully converted to propane (CH3-CH2-CH3) using a nickel catalyst, as illustrated by the reaction CH3-C≡C-H + 2H2 → CH3-CH2-CH3.
