Unformatted text preview: a. cis-1-ethyl-2-isopropylcyclohexane b. cis-1-ethyl-3-methylcyclohexane c. cis-1-ethyl-4-methylcyclohexane d. trans-1-ethyl-2-isopropylcyclohexane e. trans-1-ethyl-3-methylcyclohexane 3. The most stable form of the common sugar glucose contains a six membered ring in the chair conformation with all the substituents equatorial. Draw the most stable conformation of glucose. 4. Trans-1,2-dimethylcyclobutane is more stable than cis-1,2-dimethylcyclobutane, but cis 1,3-dimethylcyclobutane is more stable than trans-1,3-dimethylcyclobutane. Use drawings to explain this observation....
