forces between molecules

Forces in order of strength

Van der waals

Dipole-dipole

Hydrogen

Van Der waal

Temporary/induced dipole acts between all atoms and molecules caused by electron distortion

Electron distortion

Movement of electrons to one side of the atom

electron number in van der waals forces

More electrons= more electron distortion

Temporary dipole

Temporary polarity caused by electron distortion

How van der waal forces work

Electron distortion creates a temporary dipole in a molecule/atom which induces a dipole in another molecules /atoms and these dipoles in different molecules/atoms attract

Dipole-dipole

Hydrogen

Act between certain molecules

Dipole-dipole

Attraction that Occurs between molecules that posses an overall dipole

Overall dipole

Molecules where charge is shared unevenly due to electronegativity

Hydrogen bonds

Occurs when a molecule has a very electronegative atom (fluorine oxygen and nitrogen) and a lone pair

how hydrogen bonding works

Covalent bond between hydrogen and the very electronegative atom
