To model methanol (CH₃OH), we need to consider its molecular composition:
- C (carbon): 1 atom
- H (hydrogen): 3 atoms
- O (oxygen): 1 atom
Now, let's match these with their respective colors:
- Carbon (C): gray
- Hydrogen (H): white
- Oxygen (O): red
So, the molecular model of methanol would consist of:
- 1 gray sphere (for carbon)
- 3 white spheres (for hydrogen)
- 1 red sphere (for oxygen)
This corresponds to the first option:
one gray sphere, four white spheres, one red sphere is incorrect since there should only be three white spheres, not four.
The correct description for the model of methanol (CH₃OH) would be:
one gray sphere, three white spheres, one red sphere.
This was omitted from the original options but describes the composition accurately.
