Which of the following terms best describes the pair of
compounds shown: enantiomers, diastereomers, or the same
compound?
Stereochemistry is the study of the three-dimensional structure of molecules. The cand trans isomers are forms of stereoisomers, differing structurally only in the location of the stoms of the molecule in three-dimensional space. Such stereostomers can have different physical and chemical properties. Stereochemistry is of particular interest to biochemists because the reactivity and toxicity of molecules change with their stereochemistry Most body...
