To model methanol (CH₃OH), we need one carbon (C), four hydrogen (H), and one oxygen (O).
According to the atom colors in the molecular model:
- Carbon (C) is gray
- Hydrogen (H) is white
- Oxygen (O) is red
Therefore, a model of methanol will have:
- One gray sphere (for carbon)
- Four white spheres (for the hydrogens)
- One red sphere (for oxygen)
So, the correct option that describes the model of methanol, CH₃OH, is:
one gray sphere, four white spheres, one red sphere.
