Dipole Moments

[Goyama_2A]

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

[Samuel Tzeng 1B]

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

[Isabella Dal Porto 1H]

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.

[Rebecca Epner 4A]

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.
