What is the number of moles of H atoms required for complete reduction of one mole acetonitrile?

Step-by-step solution

Reduction of acetonitrile follows the general catalytic hydrogenation reaction for nitriles: R-C N + 2H₂ catalyst R-CH₂NH₂ . For acetonitrile ( CH₃CN ): CH₃-C N + 2H₂ CH₃CH₂NH₂ . Each mole of H₂ contains 2 moles of hydrogen atoms, so 2 moles of H₂ yield 2 2 = 4 moles of H atoms. The complete reduction of one mole of acetonitrile requires 4 moles of H atoms .
