Q.
Chloroform reacts with concentrated $HNO_{3}$ to give
Haloalkanes and Haloarenes
Solution:
When chloroform reacts with $HNO_{3}$ product formed are chloropicrin or tear gas and water.
$\underset{\text{chloroform}}{CHCl_{3}} +\underset{\text{conc\,nitric\,acid}}{HCO_{3}} \to \underset{\text{chloropicrin}}{CCl_{3}NO_{2}} +\underset{\text{watre}}{H_{2}O}$
