Question

$3CuO+2N{H}_3\to 3Cu+3H_{2}O+N_2$
In this reaction $N{H}_3$:

• A. behaves as a base
• B. acts as an acid
• C. acts as an oxidising agent
• D. acts as a reducing agent

Answer 1

The correct option is A behaves as a base

$N{H}_3$ is a Lewis base. Base are those species which has the tendency to either accept proton or to donate an electron. Because $N$ atom contains a lone pair of electrons so $N{H}_3$ acts as a Lewis base.
