and

\mathrm{CHC}{\mathrm{l}_3}\;

can be distinguished by the action of:

View answer and explanation

Correct option: A

R\mathrm{N}{\mathrm{H}_2} + \mathrm{KOH\;alc}.

Option A is correct because chloroform reacts with primary amines in the presence of alcoholic KOH to form isocyanides (carbylamines) which have a foul smell, while carbon tetrachloride does not react.
