Draw one planar structure each for the following compounds using dashed or solid wedges to show the stereochemistry of the substituent groups. To be graded properly, include the hydrogen atoms on the chirality centers (asymmetric carbons). cis-1,3-dimethylcyclohexane trans-1,3-dimethylcyclohexane
Draw one planar structure each for the following compounds using dashed or solid wedges to show the stereochemistry of the substituent groups. To be graded properly, include the hydrogen atoms on the chi centers (asymmetric carbons) cis-1,3-dimethylcyclohexane trans-1,3-dimethylcyclohexane
A trisubstituted cyclohexane compound is given below in its chair conformation. Draw the corresponding planar (overhead) representation, using wedges and hashed bonds to indicate the substituent positions. To be graded properly, include the hydrogen atoms on the chirality centers (asymmetric carbons). Be sure that both wedges/hashed bonds are drawn on the outside of the ring, or else the stereochemistry may be interpreted as square planar.

Draw the structure of 2R 3R)-2,3-dichloropentane. Use bold or hashed wedges to indicate the configuration at asymmetric C atoms. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. Show the appropriate stereochemistry by choosing the dashed or wedged buttons and then clicking a bond on the canvas. 2 . H: 1200 mAh 31.+07 Marvin JS ChemAxon LADDODOOD
