Arrange the following substances in order of increasing boiling point: N₂, H₂, NH_3,PH₃

Question

Quizplus · Accepted Answer

Hydrogen (H2) and nitrogen (N2) are nonpolar molecules with weak London dispersion forces, resulting in low boiling points. Ammonia (NH3) has hydrogen bonding, which significantly increases its boiling point compared to phosphine (PH3), which has weaker dipole-dipole interactions. Thus, the order is H2 < N2 < PH3 < NH3.
