7. Draw and label both cis and trans isomers of 1-ethyl-4-methylcyclohexane. (10 pt) a. For each isomer, draw the two possible chairs and indicate which of the two will be preferred and by how much (a lot or little). (5 pt) b. Which of the four is considered the most stable (label as "best") and which is least stable ("worst")? (3 pt) c. Clearly label 1,3-diaxial interactions, if present, in any of the conformations? (2 pt) Cis Trans
