In molecules that apply, there is a partial negative charge on one end of a functional group while there is a partial positive charge on the other. This causes the opposite sided charges of molecules to attract to one another

Occurs between non-polar molecules

Between polar mol- ecules (unequally shared)

Generally between polar molecules

molecules that have unequally shared electrons resulting in absolute positive or negative charged functional groups

The opposite charges of molecules attract to each other

A bond involving only H bonded to either O,N, or F. Opposite (partial) charged portions of one functional group join with the other.

If an electron is found on one side of a molecule, there's a momentary attraction, as a positive area of one molecule is exposed to a negative area of one molecules, therefore attracting. A negative

Intermolecular forces (Forces between molecules )

Ionic-dipole

Moderate (quite strong) forces (10-20+)

Hydrogen-bonding

Moderate (quite strong) forces (15-20+)

Polar (a type of dipole case)

Dipole-Dipole

Somewhat strong forces (2-15)

Polar

Dispersion

weak/temporary forces (0-3)

Non-polar
