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
