Question

Chloropicrin is obtained by the reaction of:

A

Nitric acid on chlorobenzene

B

Chlorine on picric acid

C

Nitric acid on chloroform

D

Steam on carbon tetrachloride

Step-by-Step Solution

Chloropicrin (CCl3NO2\text{CCl}_3\text{NO}_2), also known as nitrochloroform or tear gas, is obtained when chloroform (CHCl3\text{CHCl}_3) reacts with concentrated nitric acid (HNO3\text{HNO}_3). In this reaction, the hydrogen atom of chloroform is replaced by the nitro group (NO2-\text{NO}_2) from nitric acid. The chemical equation is: CHCl3+HNO3ΔCCl3NO2+H2O\text{CHCl}_3 + \text{HNO}_3 \xrightarrow{\Delta} \text{CCl}_3\text{NO}_2 + \text{H}_2\text{O}

Exam Context & Concepts Covered

This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from Haloalkanes and Haloarenes. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
