We’re being asked to draw and compare the ring flip conformer for the given structure:
Recall that when doing a chair flip, groups in the equatorial position are switched to axial and vice-versa. However, the orientation of each group (up or down) remains the same.
Also recall that:
• axial groups = ↑ energy or ↓ stability
• equatorial groups = ↓ energy or ↑ stability
For this problem, we need to do the following steps:
Step 1: Draw the chair flip for the given structure.
Step 2: Compare the energy and stability of the two conformers.
Step 3: Draw the line-angle formula for the compound.
