Q. Which one of the following compounds will dissolve in an alkali solution after it has undergone reaction with Hinsberg reagent?
A) $CH_{3}NH_{2}$
B) $\left( CH_{3} \right)_{3}N$
C) $\left( C_{2}H_{5} \right)_{2}NH$
D) $C_{6}H_{5}NHC_{6}H_{5}$
Explanation
(a)
$CH_{3}NH_{2} + C_{6}H_{5}SO_{2}CI \rightarrow C_{6}H_{5}SO_{2}NHCH_{3}\underset{(alkali)}{\overset{NaOH}{\rightarrow}}C_{6}H_{5}SO_{2}N(Na)CH_{3}$
1${^\circ}$ amine hinsberg’s N-methyl benzene soluble sodium salt
Reagent sulphonamide
