Isomer types The following tree diagram should help you identify the most appropriate term to describe the relationship between a pair of structures based on . - Identify structural cons.utional isomers by their bonding patterns. The atoms of the compounds are the same but they are connected in such a way as to make different functional groups. An example would be n-butane and isobutane. N-butane is a straight hydrocarbon chain with four carbons while isobutene isnched..This discusses the types of isomers including cons.utional, conformational, enantiomers, diastereomers .
