(The order of bonding in the isomers is the same), but the arrangement of the atoms in space is different in each isomer.

Same molecular formula, but properties change i.e butane and methylpropane. As the number of carbons increases so does the number of possible isomers.

This can occur where there is an atom, or group of atom, substituted in a carbon chain or ring.

Sometimes it is possible for compounds with the same molecular formula to have different functional groups, and because they have different functional groups they will belong to different homologous series.
