The chemical formula of 'tear gas' is
1 \(\mathrm{COCl}_{2}\)
2 \(\mathrm{CO}_{2}\)
3 \(\mathrm{Cl}_{2}\)
4 \(\mathrm{CCl}_{3} \mathrm{NO}_{2}\)
Explanation:
Chloropicrin is also known as tear gas. It is obtained by the reaction of chloroform with nitric acid. \(\mathrm{CHCl}_{3}+\mathrm{HNO}_{3} \rightarrow \underset{\substack{\text { Chloropicrin } \\ \text { (tear gas) }}}{\mathrm{CCl}_{3} \mathrm{NO}_{2}}+\mathrm{H}_{2} \mathrm{O}\)
