ak18 Posted July 24, 2013 Report Share Posted July 24, 2013 The intermolecular forces between molecules of PCl5 are larger than the ones in PCl3 - thus a higher boiling point the PCl5 molecule is much larger than the PCl3 and the larger number of protons and electrons in the PCl5 molecule make the dispersion attractions greater. http://www.chemguide.co.uk/atoms/bonding/vdw.htmlthis website should help give you a clearer answer though. 3 Reply Link to post Share on other sites More sharing options...
