An organic compound has C = 40%, H = 6.67%, and O = 53.3%. What is the empirical formula of the compound? (MDCAT 2023)

Verified Answer & Explanation⌄

Correct Answer: C) CH₂O

Concept Explanation

For 100 g: C = 40/12 ≈ 3.33 mol, H = 6.67/1 = 6.67 mol, O = 53.3/16 ≈ 3.33 mol. Dividing by 3.33 gives C:H:O = 1:2:1, so the empirical formula is CH₂O.
