Question

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

Explanation:

Step1: Analyze methanol formula

The formula $\text{CH}_3\text{OH}$ has 1 carbon (black), 1 oxygen (red), and 4 hydrogens (white).

Step2: Examine models

Check each model for correct atom - count and colors. The correct model should have 1 black, 1 red, and 4 white spheres.

Answer:

The second model (assuming the bottom - shown model in the image) as it has 1 black (carbon), 1 red (oxygen), and 4 white (hydrogen) spheres which match the molecular formula of methanol $\text{CH}_3\text{OH}$.
