Chemistry
Which option correctly describes the outcome of treating amines with TsCl in aqueous NaOH ?
A
Primary amine 
-tosyl derivative soluble in alkali; Secondary amine → N-tosyl derivative insoluble; Tertiary amine → no reaction.
-tosyl derivative soluble in alkali; Secondary amine → N-tosyl derivative insoluble; Tertiary amine → no reaction. B
Primary amine → insoluble product; Secondary amine → soluble product; Tertiary amine → no reaction.
C
Primary and secondary amines both give products soluble in alkali; tertiary amine reacts slowly.
D
All three 
react to give sulfonamides soluble in alkali.
react to give sulfonamides soluble in alkali.
Text Solution
Verified by ExpertsThe correct answer is:
A
Hinsberg test ( 
aq. NaOH ): 
amines → N-tosylamides with 
; the 
is acidic, so product dissolves in alkali. 
amines 
dialkyl sulphonamides (no 
), hence insoluble. 
amines don't form sulphonamides.
