apsmeerut.comBoiling point: PH 3 < AsH 3 < NH 3 < SbH 3 < BiH 3 Boiling point increases with increase in size due to increase in van der Waals forces. Boiling point of NH 3 is more because of hydrogen bonding. Bond angle: NH 3 (107.8°) > PH 3 (99.5°) > AsH 3 (91.8°) ≈ SbH 3 (91.3°) > BiH 3 (90°) Electronegativity of N is highest. Therefore, the lone ...

alpha.chem.umb.edu• The boiling point of H 2 should be the lowest because it is nonpolar and has the lowest molecular weight. • The molecular weights of CO, HF, and Ne are roughly the same. Because HF can hydrogen bond, however, it should have the highest boiling point of the three. • Next is CO, which is slightly polar and has the highest molecular weight.
