Review of Planar Isomerism or Constitutional Isomerism Isomerism is the study of isomers. Isos, from the Greek, means equal; while meres, parts. Isomers are compounds that have the same molecular formula but present differences in their properties due to structural differences. In the case of planar isomerism, the isomers differ by the planar structural formulas. Case Studies: chain (or nucleus) isomerism; positional isomerism; compensation isomerism (or metamerism); function (or functional) isomerism; tautomerism. Solved Exercises: (UECE 2015) 1,4-dimethoxybenzene is a white solid with an intense sweet floral odor. It is mainly used in perfumes and soaps. The number of positional isomers of this compound, counting it, is a) 2. b) 3. c) 5. d) 4. (UECE 2018) Diethyl ether (ethoxyethane) is a volatile and highly flammable liquid substance. Initially used as an anesthetic, its use was discontinued due to the risk of explosion. It currently serves as an excellent solvent for chemical experiments in laboratories. This organic compound is an isomer of an unbranched chain primary alcohol, whose name is a) butan-2-ol. b) methylpropan-2-ol. c) butan-1-ol. d) pentan-1-ol. (UFPR 2010) Consider the following substances: Select the alternative that presents the type of isomerism presented by these substances. a) Functional. b) Chain. c) Position. d) Metamerism. e) Tautomerism.
