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°CThe 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
