Polarisation of the bond in covalent molecules:
- The sign delta + and delta - show that the electrons are not evenly distributed between the two atoms becuase one attracts more the other (being more electronegative)
- FONClBrICH - is a good made up word to remember the electronegativities with F being the most electronegative and H being the least electronegative.
- Weak between forces
- short range
- Permenant dipole-dipole forces : occur between molecules with permenant dipoles so the slightly possitive side of one will attract the slightly negative of another this is through electrostatic attractions
- Instantaneous dipole-induced dipole forces / Van der waals forces occur between all atoms and molecules but they're only really significant if they have…
