Solution: Using the cyclohexane scaffold shown below, draw the structural formula of all-cis-1-ethyl-2,4 difluorocyclohexane (all-cis means that all three substituents point in the same direction). Now, draw both of the chair conformations of this molecule and circle the more stable conformation (equatiorial preference energies: –F: 0.2 kcal mol−1; –CH3CH2: −1.9 kcal mol−1).

Problem

Using the cyclohexane scaffold shown below, draw the structural formula of all-cis-1-ethyl-2,4 difluorocyclohexane (all-cis means that all three substituents point in the same direction). Now, draw both of the chair conformations of this molecule and circle the more stable conformation (equatiorial preference energies: –F: 0.2 kcal mol−1; –CH3CH2: −1.9 kcal mol−1).
