Geometric and optical isomers we can now return to compounds that differ only in their 3-dimensional structures geometric isomers have the same structural formulas but differ in the arrangement of groups at a single atom, at double bonds, or in rings. Isomerism is introduced and explained with numerous examples-case studies 141 defines and describes examples of four types of structural isomerism, namely (a) chain isomerism, (b) positional isomerism, (c) functional group isomerism and (d) tautomerism.
