Structrue
simple molecular
Why has P4O10 have a higher m.p than SO2
bigger molecule with more electrons so stronger vdw forces between molecules and more energy needed to break
Bonding
covalent but weak vdws
Low melting point because
weak vdw forces between molecules which require less energy to break
