The first step refers to the image.

In case of compound (I) and (II) , electron density in 1

′

amine is less than 2

′

amine and two methyl group attached to 2

′

amine having +I effect. i.e, why primary amine have more stable intermolecular H-bonding than secondary amine. In 1

′

amine have 2 H-atom and 2

′

amine have only one H-atom for intramolecular H-bonding. So, the boiling point of 1

′

amine is higher than the 2

and 3

amine. Order⇒1
