Question

Procedure B. 1. Build two models of 1, 2-dimethyleyclopentane. The two methy can be on the same face or opposite faces of the ring. No matter how t molecule is twisted, they cannot be superimposed on each other. These compounds are stereoisomers of each other. 2. When two groups are present, the prefix cis (same face) or trans (opposite face) can be used in IUPAC nomenclature to specify which stereoisomer is being considered. For drawings, a solid wedged line in the bond to a carbon is coming out of the page and a dashed wedged line indicates the bond going into the page. 3. Write the IUPAC name of the compounds below, including cis or trans where appropriate. 4. For two of the compounds above, cis or trans is not needed. Circle those compounds and state why. 5. diethylcyclohexane. 6. 7. because all of the bond angles around the carbon atoms are at 109.5° and all carbon atoms are in the more stable staggered conformation. Cyclohexane is the only cyclic structure that allows all the bond angles around each carbon to Draw the wedge/dashed bond line representation of trans-1,3 Build two models of cyclohexane. The chair conformation is the most stable conformation of cyclohexane be 109.5, thus is the only ring that adopts a true chair conformation. Form the chair conformation with both of your cyclohexane models. Look down each carbon carbon bond and verify that all carbons are in a staggered conformation.
