Q. Assertion A primary amine has higher boiling point than any tertiary amine.
Reason A tertiary amine has greater number of $N - H$ bonds for $H$-bonding.

AIIMSAIIMS 2010

Solution:

Primary amines have two $N - H$ bonds, thus have the ability of $H$-bonding while such an ability is not found in tertiary amines because of the absence of $N - H$ bonds. Thus, primary amines have higher boiling point than tertiary amines having same molecular mass. Hence, Assertion is true but Reason is false.
