Do a ring flip of both *Draw the two conformation of the cis and trans cyclohexane structures above *List the number of axial and equatorial substituents for both the cis and trans *Which isomer is more stable overall, cis or trans? Why? 2. Make a model cis-1,3-dimethylcyclohexane and trans-1,3-dimethylcyclohexane. Do a ring flip *Draw the two conformation of the cis and trans cyclohexane structures above *List the number...
Which of the statements below correctly describes the chair conformations of cis–1,3–dimethylcyclohexane? a. The two chair conformations are of equal energy. b. The higher energy chair conformation (least stable) contains one axial methyl group and one equatorial methyl group c. The lower energy chair conformation (most stable) contains one axial methyl group and one equatorial methyl group d. The higher energy chair conformation (least stable) contains two axial methyl groups Please show work for the correct answer.
1. Now construct cis-1,2-dimethylcyclohexane in the chair conformation and draw it. Perform the ring flip and draw that conformation. Which of the two conformations is preferred? This compound is meso, find the conformation that accounts for this? 2. Construct and draw trans-1-ethyl-2-methylcyclohexane in the chair conformation. Perform the ring flip and draw that conformation. Which conformation is preferred/most stable? Why? Construct and draw the cis isomer in the most stable chair conformation. Perform the ring flip and draw that conformation....

Help Organic Chem part 4 Cyclohexane Conformations Put your model of cis-1,3-dichlorocyclohexane into a chair conformation. Sometimes the easiest way to do this is by adjusting it to make the axial bonds alternate up and down. Now convert it to the other chair structure, asking the instructor for help if needed. Is the second conformation still cis or is it trans? Are the two conformations the same or are they different? Draw chair structures of both conformations making sure to...
