Which of the following conformers has the highest energy (is the least stable)?

Draw the two chair conformers for each of the following and indicate which conformer is more stable:

e. cis-1-ethyl-3-isopropylcyclohexane

For each of the following compounds, determine whether the cis isomer or the trans isomer is more stable.

a.

b.

c.

Predict which side of the equilibrium is favored for each of the chair–chair interconversions (ring flips) shown.

(c)

Predict which side of the equilibrium is favored for each of the chair–chair interconversions (ring flips) shown.

(a)

Draw the MOST STABLE conformation of cis-1-tert-butyl-4-methylcyclohexane.

Draw the LEAST STABLE conformation of trans-1-tert-butyl-3-neopentylcyclohexane.

Draw the most stable conformation of

c. cis-1-tert-butyl-4-isopropylcyclohexane.
