Which is more stable, a 1,4 trans disubstituted cyclohexane or its cis isomer? Explain

On the following energy diagram, identify the energy level of the cyclohexane conformation shown in the box. Energy (kJ/mol) A) I B) II CLU ||| IV Conformations 2

Consider 1,2-dimethylcyclohexane. a.Draw structures for the cis and trans isomers using a hexagon for the sixmembered ring. b. Draw the two possible chair conformations for the cis isomer. Which conformation, if either, is more stable? c. Draw the two possible chair conformations for the trans isomer. Which conformation, if either, is more stable? d.Which isomer, cis or trans, is more stable and why?

Here is one cis,trans isomer of 3,5-dimethylcyclohexanol. Complete the alternative chair conformations. OH ОН OH 3. CH3
