Single Choice
The amine which reacts with p-toluenesulfonyl chloride to give a clear solution which on acidification gives insoluble compound is:
A$$C_2H_5NH_2$$
Correct Answer
B$$(C_2H_5)_2NH$$
C$$(C_2H_5)_3N$$
D$$CH_3NHC_2H_5$$
Solution
The amine which reacts with p-toluenesulphonyl chloride to give a clear solution which on acidification gives insoluble compound is a primary amine such as ethyl amine $$\displaystyle C_2H_5NH_2$$.
$$\displaystyle C_2H_5NH_2 +CH_3-C_6H_4-SO_2-Cl \xrightarrow {OH^-} CH_3-C_6H_4-SO_2-NHC_2H_5\\ \: \xrightarrow {KOH} CH_3-C_6H_4-SO_2-N^-C_2H_5K^+ \xrightarrow {H^+} CH_3-C_6H_4-SO_2-NHC_2H_5$$.
It is Hinsberg's test used to distinguish between primary, secondary and tertiary amine.
Option A is correct.
