Define the term isomer
WebThe structural basis of enantiomerism is called chirality. Enantiomers are a pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other. Enantiomers are in every other respect chemically identical. A pair of enantiomers is distinguished by the direction in which when dissolved ... Web1. One of two or more substances displaying isomerism, for example, l-glucose and d-glucose or citrate and isocitrate. Compare: stereoisomer. 2. One of two or more nuclides having the same atomic and mass numbers but differing in energy states for a finite period of time, for example, 99m Tc and 99Tc. [iso- + G. meros, part]
