The product of an amine ' $\mathrm{X}$ ' with benzene sulphonyl chloride produces the product which is insoluble in alkali. The product of ' $\mathrm{X}$ ' with ethanoyl chloride is
  1. $\mathrm{C}_6 \mathrm{H}_5 \mathrm{NHCOCH}_3$
  2. $\mathrm{C}_6 \mathrm{H}_5 \mathrm{~N}\left(\mathrm{CH}_3ight) \mathrm{COCH}_3$
  3. $\mathrm{C}_6 \mathrm{H}_5 \mathrm{~N}\left(\mathrm{CH}_3ight) \mathrm{CH}_2 \mathrm{CH}_3$
  4. $\mathrm{C}_6 \mathrm{H}_5 \mathrm{NHCH}_2 \mathrm{CH}_3$

Solution

A secondary amine gives an insoluble compound upon reaction with Hinsberg reagent.
Thus, ' $\mathrm{X}$ ' will be
