Final answer:
The chemical formula CCl₂F₂ represents an organic molecule as it contains carbon and halogen atoms and fits the criteria for organic compounds.
Step-by-step explanation:
The chemical formula that represents an organic molecule among the given choices is CCl₂F₂. Organic molecules primarily consist of carbon and hydrogen atoms, and they may also contain other elements like oxygen, nitrogen, sulfur, phosphorus, and halogens. CCl₂F₂, also known as dichlorodifluoromethane, consists mostly of a carbon atom bound to chlorine and fluorine atoms, which fits the criteria for an organic compound. On the contrary, 4H₂O (water), Al₂O₃ (aluminum oxide), and H₂SO₄ (sulfuric acid) do not have carbon as their main component, thus are considered inorganic.
