Q6 / 90 · JEE Main 2024 (09 Apr Shift 1) · Chemistry

On reaction of Lead Sulphide with dilute nitric acid which of the following is not formed?

A
Nitric oxide
Correct answer
B
Nitrous oxide
C
Lead nitrate
D
Sulphur

Solution

$\mathrm{PbS}+\mathrm{HNO}_3 \rightarrow \mathrm{Pb}\left(\mathrm{NO}_3\right)_2+\mathrm{NO}+\mathrm{S}+\mathrm{H}_2 \mathrm{O}$
Nitrous oxide $\left(\mathrm{N}_2 \mathrm{O}\right)$ is not formed during the reaction.

Hence, the correct answer is option: 'B'.
