The elements of group 5A, the nitrogen family, form compounds with hydrogen having the boiling points listed below:

         SbH3–17°C, AsH3–55°C, PH3–87°C, NH3–33°C

The first three compounds illustrate a trend where the boiling point decreases as the mass decreases; however, ammonia (NH3) does not follow the trend because of:



▸ dipole-dipole attraction.

▸ metallic bonding.

▸ hydrogen bonding.

▸ London dispersion forces.

▸ ionic bonding.
