the molecular formula for methanol is ch₃oh. which model shows methanol? (black = carbon; red = oxygen…

Explanation:

Step 1: Identify methanol's atomic composition.

Methanol ($CH_3OH$) consists of 1 carbon atom, 4 hydrogen atoms, and 1 oxygen atom.

Step 2: Note atom color assignments.

The problem states: Carbon (C) = black, Oxygen (O) = red, Hydrogen (H) = white.

Step 3: Analyze the top model's atoms and connectivity.

The top model shows 1 black sphere (carbon), 1 red sphere (oxygen), and 4 white spheres (hydrogen). The black sphere is bonded to three white spheres and the red sphere. The red sphere is bonded to one white sphere and the black sphere. This is consistent with $CH_3OH$.

Step 4: Analyze the bottom model's atoms and connectivity.

The bottom model also shows 1 black sphere (carbon), 1 red sphere (oxygen), and 4 white spheres (hydrogen) with the same connectivity as described in Step 3. This is also consistent with $CH_3OH$.

Step 5: Determine the correct model.

Both models accurately represent methanol based on atomic composition, color coding, and chemical structure. As the question asks to identify which model shows methanol and both are correct representations viewed from different angles, either could be selected. For this solution, we select the top model.

Answer:

The top model.
