Question

Mixture $1^{\circ },2^{\circ },3^{\circ },$ amines can be separated by :

• A. the Hinsberg's method
• B. the Hofmann's isocyanide test
• C. fractional distillation
• D. $NaN{O}_{2}HCl$

Answer 1

Answer: (A), (C)

The correct options are
A the Hinsberg's method
C fractional distillation

Mixture of primary, secondary and tertiary amines can be separated by Hinsberg's method and fractional distillation.
They give different products with Hinsberg's. These products differ in solubility. Hence, they can be separated with Hinsberg's method. They differ in boiling points. Hence they can be separated by fractional distillation.
