Answer 1

To describe a model of methanol (CH3OH), we need to identify the components based on the molecular formula:

• C (carbon): 1 atom
• H (hydrogen): 3 atoms
• O (oxygen): 1 atom
• H (hydrogen): 1 atom (from the hydroxyl group)

This gives us a total of:

• 1 gray sphere (for carbon)
• 4 white spheres (for 4 hydrogen atoms: 3 from CH3 and 1 from OH)
• 1 red sphere (for oxygen)

Thus, the correct option to describe a model of methanol (CH3OH) is:

one gray sphere, four white spheres, one red sphere.
