To describe a model of methanol (CH₃OH), we need to identify the components based on its molecular formula.
Methanol (CH₃OH) consists of:
- 1 carbon atom (C)
- 3 hydrogen atoms (H)
- 1 oxygen atom (O)
- The hydrogen atoms are represented by white spheres, the carbon by a gray sphere, and the oxygen by a red sphere.
Putting this together, the model of methanol can be described as:
- 1 gray sphere (for carbon)
- 4 white spheres (for the 3 hydrogen atoms and the additional hydrogen from the hydroxyl group -OH)
- 1 red sphere (for the oxygen atom)
Thus, the correct option is:
**one gray sphere, four white spheres, one red sphere**.
