Which of the following has a boiling point which does not fit the general trend.
NH3
PH3
SbH3
AsH3

I am going with NH3 as i think its to do with "the larger the compound the greater the boiling point"(Vander waals forces)
Am I correct?

NH3 does not fit the general trend due to the greater number of inter-molecular forces required to release molecules from the liquid to gaseous state. Due to the N and H, the NH3 molecule exhibits hydrogen bonding, which is much stronger than the dipole-dipole forces between the rest of the molecules.
