Question

Which of the following statement(s) is/are correct regarding Hinsberg's test?

• A. It is used to distinguish aliphatic and aromatic primary amines
• B. It is used to distinguish primary and secondary amines
• C. It is used to distinguish primary and secondary alcohols
• D. Both (b) and (c)

Answer 1

The correct option is B It is used to distinguish primary and secondary amines

Hinsberg'st test is used to distinguish between primary, secondary and tertiary amines.
It does not distinguish aliphatic and aromatic primary amines.

Sulphonamides formed from primary amine is soluble in alkali.
Sulphonamides formed from secondary amine is insoluble in alkali.
Sulphonamides are not formed by tertiary amines. So it is the best reagent to distinguish all the three types of amines.
