Ionic and covalent compounds


	Ionic and covalent compounds
	Similarities (e.g sodium chloride) crystalline solids high melting and boiling points do not evaporate easily consist of ions conduct electricity when melted or dissolved sometimes dissolve in water insoluble in organic solvents	Differences (e.g. methane) solids, liquids and gases low melting and boiling points may evaporate easily consist of molecules non-electrolytes: do not conduct electricity may not dissolve in water soluble in most organic solvents, e.g. alcohol, ether, petrol
	Overall comparison Ionic compounds are on the left. Covalent compounds are on the right.
