Draw the most stable chair conformation for cis-1-isopropyl-2-methylcyclohexane

What is the key factor to consider when drawing the most stable chair conformation for cis-1-isopropyl-2-methylcyclohexane?

a. Position of the isopropyl group
b. Position of the methyl group
c. Both a and b

Answer:

c. Both a and b

To draw the most stable chair conformation for cis-1-isopropyl-2-methylcyclohexane, it is crucial to consider the positions of both the isopropyl group and the methyl group. By placing these substituents in the correct positions, we can minimize steric hindrance and maintain the cis configuration of the molecule.

When both the isopropyl group and the methyl group are positioned equatorially, we can achieve the most stable chair conformation. This arrangement helps to reduce any unfavorable interactions between the bulky substituents and the hydrogens on the cyclohexane ring.

Therefore, when drawing the chair conformation for cis-1-isopropyl-2-methylcyclohexane, be sure to place both the isopropyl and methyl groups in equatorial positions to optimize stability.
