Question

the chemical formula for methanol is \ce{ch_{3}oh}. which of the following models could be used to represent methanol? a b c d

Explanation:

Step1: Count atoms in CH₃OH

CH₃OH has 1 C, 4 H, 1 O atoms.

Step2: Match to model

Model A has 1 central gray (C), 4 white (H), 1 red (O) atoms, matching the formula's atom count and structure (C bonded to 3 H and an -OH group). Models B (long carbon chain), C (multiple O/C atoms), D (too few H atoms) do not match.

Answer:

A. [The model with 1 gray (C), 4 white (H), 1 red (O) atoms arranged as C bonded to 3 H, 1 OH group]
