Amines - Identification of Primary, Secondary and Tertiary Amines

Distinguish between the following pairs of compounds: Aniline and N-methylaniline

 Describe Hinsberg method for the identification of primary, secondary and tertiary amines. Also write the chemical equations of the reactions involved.

Describe a method for the identification of primary, secondary and tertiary amines. Also write chemical equations of the reactions involved.

Arrange the following in the increasing order of their boiling points:

A: Butanamine

B: N, N-Dimethylethanamine

C: N- Etthylethanaminamine

Given below are two statements labelled as Assertion (A) and Reason (R).

Assertion (A): Tertiary amines are more basic than corresponding secondary and primary amines in gaseous state.

Reason (R): Tertiary amines have three alkyl groups which cause +I effect.

Select the most appropriate answer from the options given below:

Give plausible explanation for each of the following:

Why do primary amines have higher boiling point than tertiary amines?
