Q2: Total number of alkali insoluble solid sulphonamides obtained by reaction of given 
amines with Hinsberg's reagent is ________. 
Aniline, N-Methylaniline, Methanamine, N,N-Dimethylmethanamine, N-Methyl 
methanamine, Phenylmethanamine, N-propylaniline, N-phenylaniline, 
N,N-Dimethylaniline, Allyl amine, Isopropyl amine 
A: 8 
B: 5 
C: 2 
D: 4 
Answer: D 
Explanation: 
In Hinsberg’s test, the sulphonamide formed from a 2° (secondary) amine is alkali insoluble. 
This is because a 2° amine has no N–H left in the sulphonamide, so it cannot form a soluble salt 
with alkali. 
So, we have to count the 2° amines from the given list. 
Ph – NH – CH 3, Me – NH – Me, 
Ph – NH – CH 2 – CH 2 – CH 3, Ph – NH – Ph 
 
Q3: Given below are two statements: 
Statement I : The dipole moment of R-CN is greater than R-NC and R-NC can 
 
Statement II : R–CN hydrolyses under acidic medium to produce a compound which on 
treatment with SOCl 2, followed by the addition of NH 3 gives another compound (x). This 
compound (x) on treatment with NaOCl/NaOH gives a product, that on treatment with 
CHCl 3/KOH/? produces R–NC 
In the light of the above statements, choose the correct answer from the options given 
below 
A: Both Statement I and Statement II are false 
B: Statement I is false but Statement II is true 
C: Statement I is true but Statement II is false 
D: Both Statement I and Statement II are true
