Isomers have the same molecular formula, but their molecules are different. Their differences arise in a number of ways. Structural isomerism occurs when the atoms are bonded together in a different order. Stereoisomerism arises when the molecules are not superimposable because their atoms are orientated differently in space. Stereoisomers have the...

Isomerism is a chemical term first used by Berzelius in 1831. Substances which have the same percentage composition and the same molecular formulae are regarded as isomeric, e.g. ethyl alcohol and dimethyl ether, which differ considerably in chemical and physical properties, have the same formula, CaHgO. The isomerism is supposed to be due to diffe...
