Although PH3 is a larger molecule with greater dispersion forces thanammonia, NH3 has very polar N-H bonds leading to strong hydrogen bonding. This the dominant intermolecular force and results in a greater attraction between NH3molecules than there is between PH3molecules.

❤⭐..REASON:-..⭐❤
- ❤.. Unlike molecules are not associated through hydrogen bonding in liquid state.
- ❤.. That is why the boiling point of is lower than.
