4. Alkanes and Cycloalkanes

For each chair on the left, place the substituents on the flipped chair. [Recall that the axial/equatorial designation changes from one chair to the next, but the carbon to which the substituent is attached does not.]

(f)

Which of the following structures represent the same compound? Which ones represent different compounds?

(e)

Which is the most stable chair conformation of ${\mathrm{trans}}_{1,2}$-dimethylcyclohexane?

When $\mathrm{cyclohexane}$ undergoes a chair flip, what happens to the positions of axial and equatorial hydrogens on each $\mathrm{carbon}$ atom?

Which of the following statements correctly describes the result of a chair flip in $\mathrm{cyclohexane}$?

For each chair on the left, place the substituents on the flipped chair. [Recall that the axial/equatorial designation changes from one chair to the next, but the carbon to which the substituent is attached does not.]

(e)

Which statement best describes the relationship between the two chair conformations of ${\mathrm{cyclohexane}}_{}$?

Determine if the following pairof chairs are identical, conformers or different.

Determine if the following pairof chairs are identical, conformers or different.
