Chapter 27

. Give a chemical test and the reagents used to distinguish between the following pair of compounds: Ethylamine and diethylamine.

An organic compound \(A\), containing \(\mathrm{C}, \mathrm{H}, \mathrm{N}\) and \(\mathrm{O}\), on analysis gives \(49.32 \%\) carbon, \(9.59 \%\) hydrogen and \(19.18 \%\) nitrogen. \(A\) on boiling with \(\mathrm{NaOH}\) gives off \(\mathrm{NH}_{3}\) and a salt which on acidification gives a monobasic nitrogen free acid \(B\). The silver salt of \(B\) contains \(59.67 \%\) silver. Deduce the structures of \(A\) and \(B\).

Arrange the following : (i) methylamine, dimethylamine, aniline, N-methylaniline in incerasing order of base strength.

Write balanced equations for the following reaction : Acetamide is reacted with bromine in the presence of potassium hydroxide.
