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?

Draw the most stable conformation for; a. trans-1-chloro-3-methylcyclohexane b. cis-1-ethyl-2-isopropylcyclohexane c. trans-1-bromo-4-ethylcyclohexane d. cis-2-bromo-1-methylcycclohexane Sppecifically, show the ring flipping and calculate the strain using the table given in the power point slides.
6. Build the cyclobutane ring and study the angle strain and torsional strain. Draw the structures to explain these factors. 7. The conformation of cyclobutane is slightly folded. Folding gives partial relief from the eclipsing of bonds, as shown in the Newman projection. Compare this actual structure with the hypothetical planar structure. Draw the relevant structures. 8. 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 the molecular models to find the reasons for...
