STRUCTURAL ISOMERISM (same molecular formula but different structural formula)

Positional Isomerism - the same functional group appears in different positions

Functional Group Isomerism - the functional groups are different

Chain Isomerism - the chain lengths are different ie branched or unbranched

STEREOISOMERISM (atoms are bonded in the same order but have different spatial arrangements)

E/Z Isomerism - E = opposite (the different groups are on opposite sides of the molecule)

Z = together (the different groups are on the same side of the molecule)

In order to have E/Z isomerism there must be two different groups on the 2 C's of the C=C…
