Question

How many water molecules are formed as the by product of reduction of one molecule of nitropropane to one molecule of propanamine, with hydrogen gas in Pt catalyst?

(a) 1

(b) 2

(c) 3

(d) 4

I had been asked this question during an online interview.

I'd like to ask this question from Preparation of Amines in chapter Amines of Chemistry – Class 12

Answer 1

The correct answer is (b) 2

To elaborate: One molecule of nitropropane reacts with 3 molecules of hydrogen gas (H2) in the presence of Ni/Pt/Pd catalyst to form one molecule of propanamine along with two molecules of water.
