2019]
Text Solution
Verified by ExpertsA
Secondary amines on reaction with Hinsberg's reagent (benzene sulphonyl chloride) forms
-dialkyl benzene sulphonamide.
The product formed is not acidic as no H -atom is attached to N. Thus, it is insoluble in alkali.
The reaction of 
amine given in option takes place as follows:
On the other hand, 
amines react with Hinsberg's reagent to yield N -alkyl benzene sulphonamide which is soluble in alkali and 
amines do not react with 
. The remaining options contain 
and 
amines.
