london dispersion

Describe ionic intermolecular forces

between ions (charged particles) and are solid at room temp

Describe hydrogen bonding intermolecular forces

between hydrogen and nitrogen/oxygen/fluorine and is a covalent bond

Describe Dipole-dipole intermolecular forces 

between molecules with polar bonds, most common, and is covalent

Describe London dispersion intermolecular forces

between molecules with temporary shifts in electron clouds that leads to attraction and is nonpolar covalent and a gas at room temp

What in a bond determines how easy it is to boil or melt it

strength

Why does water do anything it does

hydrogen bonding
