Comparing Intermolecular Forces Ex. 1

Does H2O or NH3 have a higher boiling point, based on intermolecular forces?

-- draw the structures

-- both have dispersion forces, because that affects all molecules

-- both have hydrogen bonds

-- H2O has a hydrogen bonded to an O, which is stronger than an H bonded to an N

-- H2O has stronger intermolecular forces

-- stronger intermolecular forces = higher boiling point

-- H2O has a higher boiling point
