Answer:
The correct answer is Option A
Explanation:
- The boiling point of NHX3 is high due to intermolecular hydrogen bonding. In others, it varies directly with the molecular weight of the molecule due to increased van der Wall’s force. This force is least in PHX3 & highest in SbHX 3 NH3 has a higher boiling point than AsH3 and PH3 on account of H-bonding. SbH3 has the highest boiling point on account of the highest molecular weight.
