| SbH3 |
Dear student,
The Volatility of the hydrides of group 15 elements depends upon the strength of the hydrogen bond formed by them. Strength of hydrogen bond depends upon the electronegativity of the elements bonded to the hydrogen.
Electronegativity decreases down the group.
Therefore,
Volatility increases as,
NH3<PH3<AsH3<SbH3
