Question

The structure of a trisubstituted cyclohexane is shown, but no information is given about whether the groups are "up" or "down": that is, wedge and dash notation has not been used. Change the exo-cyclic bonds to represent the structure that will have the most stable chair conformation.

**Instruction:**

Change the bonds to each of the three methyl groups and to each of the three drawn hydrogens to wedges or dashes to represent the structure that will have the most stable chair conformation.

**Diagram Explanation:**

The diagram shows a cyclohexane ring in its chair conformation. Attached to the ring at different carbon atoms are three methyl groups (CH₃) and three hydrogen atoms (H). 

- The three methyl groups and hydrogen atoms extend from the carbon atoms in the ring.
- Each group/bond is drawn as a simple line, indicating a planar or undefined orientation.

To achieve the most stable chair conformation, you should convert these planar bonds into wedge and dash representations. Wedges indicate bonds coming out of the plane towards the viewer, while dashes indicate bonds going behind the plane away from the viewer. 

**Note:**

When modifying the structure for stability, axial positions (alternating up and down) usually exhibit higher steric hindrance for larger groups, while equatorial positions offer more stability for larger groups in cyclohexane chair conformations. Adjust the bonds accordingly.
