A
between neighbouring molecules
2
Q
van der Waal’s forces
A
the attraction between instantaneous and induced dipoles on neighbouring molecules
3
Q
permanent dipole-dipole attraction
A
attraction between the positive end δ+ of the permanent dipole on a molecule with the negative end δ- of the permanent dipole of a neighbouring molecule
4
Q
hydrogen bond
A
the attraction between a lone pair of electrons on a very electronegative atom (ie. N,O,F) in one molecule and a hydrogen atom in a neighbouring molecule, in which the hydrogen atom is covalently bonded to a very electronegative atom (N,O,F)
