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...
9. Draw the chair conformations of the substitute cyclohexanes showing the ring flip.. Show axial and equitorial bonds clearly. Label which conformation is most stable or if @ l-ethyl cyclohexane they are equal. O CIS-1,2-dimetyl cyclohexane © trans-1,2-dimethyl cyclohexane
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.

9. Draw two different chair conformations of cyclohexanol, showing all hydropen atoms. Identify each position as axial or equatorial 10. 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. Draw a skeletal structure of each, describe the difference between them and...
20. Name these compoands CHy 21. Draw chair structures for each of these compounds. Label cach substituent as axial or equatorial. trans-1,2-intethylcyclohexane cis-1.2-dimetlylcyclohexane 22. Draw a chair conformation of cyclohexane with one CH,CH: gruup and ene Clls group that fits cach description. 1,1-disubstituted cyclohexane with an axial CHCH: group cis-1,2-disubstituted cyeloliexane with an axial CHs group trans-1,3-disulstituted cyclohexane wilh an equatorial Cli, group trans-1,4-disubistituted cyclohexane with an equatorial CHCiH: group

1) Draw a chair conformation of cyclohexane. Then, draw and level properly all axial and equatorial positions on chair form of cyclohexane. 2) Draw chair, half-chair and boat conformations of ethyl cyclohexane and draw an energy diagram to explain their relative stability: 3) Draw two possible chair conformations for each of the mono-substituted cyclohexanes and determine their relative stability with proper explanation. OH 4) Draw two possible chair conformations for each of the di-substituted cyclohexanes and determine their...

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.
