Chapter 4, Problem 4.28P

Draw a chair conformation of cyclohexane with one ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}$ group and

one ${\text{CH}}_{\text{3}}$ group that fits each description.

a. a 1, 1-disubstituted cyclohexane with an axial ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}$ group

b. a cis-1, 2-disubstituted cyclohexane with an axial ${\text{CH}}_{\text{3}}$ group

c. a trans-1, 3-disubstituted cyclohexane with an equatorial ${\text{CH}}_{\text{3}}$ group

d. a trans-1, 4-disubstituted cyclohexane with an equatorial ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}$ group.
