Draw the 2 chair conformations, in the chair format, of cis-1,3-dimethylcyclohexane. Label which one is the least stable and which is the most stable. If they are of equal stability, clearly state that they are of equal stability.
4 4. (a) Draw the structure of the two chair forms of methylcyclohexane. Draw in all bonds (even the C-H bonds). Be sure the axial and equatorial bonds are shown correctly. On the appropriate structure, indicate the 1,3-diaxial interactions involving the methyl group. (b) Which is more stable, trans-1,3-dimethylcyclohexane or cis-1,3-dimethylcyclohexane? Why? 5. Draw the Newman projections for the anti conformation and two types of eclipsed conformations of 1,2-diiodoethane. Of the two eclipsed conformations, which is of higher energy, and...

Draw the most stable chair conformation of the following molecules, and estimate the amount of strain in each: (a) trans-1-Chloro-3-methylcyclohexane (b) cis-1-Ethyl-2-methylcyclohexane (c) cis-1-Bromo-4-ethylcyclohexane (d) cis-1-tert-Butylcyclohexane 11. Which isomer is more stable, cis-decalin or trans-decalin? Explain. 12. Glucose exists in two forms having a 36:64 ratio at equilibrium.

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...

The cyclohexane derivative shown exists primarily in the more stable of the two available chair conformations. Give the position, axial or equatorial, of each of the three groups shown in the more stable chair conformation. If a group divides its time equally between axial and equatorial positions, indicate this with ax/eq. The table of "Axial Strain Energies for Monosubstituted Cyclohexanes" found in the "Strain Energy Increments" section of the Reference tool is useful for answering this question. The choices are...
