Question

The organic compounds A, B and C are amines having equivalent molecular weight. A and B on reaction with benzene sulphonyl chloride give a white precipitate; however, the white precipitate obtained from compound B remains insoluble in NaOH.

The variation in the boiling point of A, B and C can be seen as:

विकल्प

• A > B > C

• B > A > C

• A = B > C

• C > B > A

Answer 1

A > B > C

Explanation:

A is a primary amine, B is a secondary amine and C is a tertiary amine. Primary amines have higher boiling points as compared to secondary and tertiary amines.
