Question

) Which of the following compounds will dissolve in aqueous NaOH after

undergoing reaction with Hinsberg’s reagent?

a) Ethylamine b) Triethylamine c) Trimethylamine d) Diethylamine​

Answer 1

Answer:

b is the answer

Answer 2

Answer:

the 1° amine that is ethylamine is going dissolve in aqueous NaOH after undergoing reaction with  Heisenberg is a reagent.

Heinberg's reagent is used to differentiate the amines into 1°, 2°, 3°.

another name of Heisenberg s reagent is benzene sulphonyl chloride.  

the formula of benzene sulphonyl chloride is C₆H₅SO₂Cl₂  

This leads to the displacement of the chloride and the generation of the sulfonamides.  

the reaction of the benzene sulfonyl chloride/ Heisenberg with secondary amines gives a sulfonamide product that is NOT soluble in alkali.  

so, option a) is the correct answer.
