Stereochemistry is the study of the three‐dimensional structure of molecules. The cis and trans isomers are forms of stereoisomers, differing structurally only in the location of the atoms of the molecule in three‐dimensional space. Such stereoisomers 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 reactions are stereospecific, meaning that receptor sites on cells accept only molecules with specific spatial arrangements of their atoms. Other configurations of the same chemical either will not react or may be toxic to the living being.

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...
3. Cyclic compounds The presence of the ring in all but very large ring cyclic molecules prevents full rotation of the ring atoms. For this reason, stereoisomerism may also occur in cyclic molecules. a) Prepare a model of cyclohexane, C6H12. Draw the condensed formula. b) Build a model of methylcyclohexane (C7H14) by replacing one of the hydrogens of cyclohexane with a methyl group. Draw the skeletal formula for methylcyclohexane. 2 c) How many different isomers exist for methylcyclohexane (CyH34)? d)...
A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...
