How will you distinguish between the following pairs of compounds
(i). Chloroform and carbon tetrachloride.
(ii). Benzyl chloride and chlorobenzene.

Explanation

Heat the two compounds separately with aniline and alcohol KOH. Chloroform gives pungent and irritating smell of an isocyanide while carbon tetrachloride does not.

(ii). Add a few drops of NaOH and `AgNO_(3)` separately to both the compounds. Benzyl chloride gives a white precipitate while chlorobenzene does not.
