Intermolecular Forces

Fun Fact: IMF's are much weaker than intramolecular forces

London Dispersion Forces

These are temporary attractive forces that result when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.

***Present in all molecules

Dipole-Dipole

Attractive forces between positively charged end of one polar molecule and the negatively charged end of another polar molecule

Hydrogen Bonding

A type of attractive intermolecular force that occurs when a hydrogen atom bonded to a highly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons

***N,O,F

Ion-Dipole

These are attractive forces that result from the electrostatic attraction between an ion and a neutral molecule that has a dipole. Most commonly found in solutions, especially ionic compounds dissolved in polar liquids
