Dipole Moments

What is a dipole moment and how do they affect intermolecular forces?

dipole moments occur when electrons are unequally shared, this can affect intermolecular forces as it makes parts of the molecule positively/negatively charged

Dipole moments occur when there is a separation of charge between two ions in an ionic bond or between atoms in a covalent bond. It occurs due to differences in electronegativity. Thus, the dipole moment will be larger if the difference in electronegativity is greater.

All of the above are great explanations. We denote dipole moments by drawing an arrow from the more positively charged atom pointing to the more negatively charged one.
