**Transcription and Explanation:**

**Chemical Structure:**

- The molecule is a cyclohexane ring with a CH₃ group at one position and an OH group at another.

**Tasks:**

- **a.** Draw the cis and trans isomer of the molecule above.
  - *Explanation:* In cis isomers, the CH₃ and OH groups are on the same side of the cyclohexane ring. In trans isomers, the groups are on opposite sides. Visualize the spatial arrangement in 3D to draw these isomers accurately.

- **b.** Draw the chair form of the trans isomer of the molecule.
  - *Explanation:* Cyclohexane often adopts a chair conformation to minimize steric strain. For the trans isomer, draw the chair conformation such that the CH₃ and OH groups are on different planes of the ring.

- **c.** Draw the flipped chair form of the trans isomer of the molecule.
  - *Explanation:* Flip the chair conformation to see how the CH₃ and OH groups switch positions between axial and equatorial orientations. This helps visualize steric interactions.

- **d.** What is the more stable chair form?
  - *Explanation:* In cyclohexane, equatorial positions are more stable due to less steric hindrance. Determine which chair conformation places bulkier groups like CH₃ in the equatorial position for maximum stability.

**Note:** Understanding these conformations is crucial for predicting chemical behavior and reactivity in organic molecules.
