In this variety of structural isomerism, the isomers contain different functional groups - that is, they belong to different families of compounds (different homologous series).
Example 1: Isomers in C3H6O
A molecular formula C3H6O could be either propanal (an aldehyde) or propanone (a ketone).
There are other possibilities as well for this same molecular formula - for example, you could have a carbon-carbon double bond (an alkene) and an -OH group (an alcohol) in the same molecule.
Another common example is illustrated by the molecular formula C3H6O2 . Amongst the several structural isomers of this are propanoic acid (a carboxylic acid) and methyl ethanoate (an ester).
