Question 4 1 pts The elements of group SA, 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: O Hydrogen bonding Ionic bonding O Dipole-dipole attraction London dispersion forces none of these
