Detailed Solution

Inter molecular H-bonding increases the boiling point of the compound [ In NH3]

Boiling point order :

\overset{{PH}_{3} < {AsH}_{3} < {SbH}_{3} < {NH}_{3}}{\to}

As the size of central element increases,

molecular size increases,

intermolecular attractions increases.

Hence ,we need to provide high amount of energy in the form of boiling point [heat],

Hence B.Pt increases form PH₃ to SbH₃.

Exceptionally hight B.Pt of NH₃ is due to its ability to form intermolecular hydrogen bonding.
