Vedclass · Answer

(C) The boiling points of the hydrides of Group $15$ elements are influenced by both molecular mass and hydrogen bonding.$SbH_3$ has the highest boiling point due to its large molecular mass and strong van der Waals forces.$NH_3$ has a higher boiling point than $AsH_3$ and $PH_3$ due to the presence of intermolecular hydrogen bonding.$AsH_3$ and $PH_3$ follow the trend based on molecular mass.The boiling points are: $SbH_3 (254 \ K) > NH_3 (238 \ K) > AsH_3 (211 \ K) > PH_3 (185 \ K)$.Thus,the correct order is $SbH_3 > NH_3 > AsH_3 > PH_3$.

The boiling points of the following hydrides follow the order of:
