Also indicate if the molecule is polar and if the molecule chiral. Arrange them from highest to lowest boiling point. Explanation: Boiling points of nitrogen family generally increases on moving down the group but boiling point of NH 3 is higher than PH 3 and AsH 3 due to hydrogen bonding. Stronger IM forces take more energy input to separate the liquid particles into gas, thus raising boiling point. In terms of point groups, the only chiral point groups are \(C_n\) and \(D_n\). However, boiling point of NH3 > PH3 NH3 > PH3 even though NH3 NH3 has lower molecular mass than PH3 PH3, due to the intermolecular hydrogen bonding in Ammonia that is not present in PH3 PH3 and other hydrides in Group-15.
