Final answer:
Sodium chloride (NaCl) is the most likely example of an inorganic compound, as it does not contain both carbon and hydrogen atoms, unlike the other options which are organic compounds.
Step-by-step explanation:
The example most likely to be an inorganic compound is sodium chloride, which is a salt (C). This is because an inorganic compound is a substance that does not contain both carbon and hydrogen atoms. While a great many inorganic compounds do contain hydrogen, such as water (H₂O) and the hydrochloric acid (HCl) produced by your stomach, and a few contain carbon atoms, like carbon dioxide (CO₂), they do not contain both elements together as in organic compounds. Methane (CH₄) and glucose (C₆H₁₂O₆) are examples of organic compounds as they contain both carbon and hydrogen atoms. Human DNA, which contains a vast array of carbon-hydrogen bonds, is also an organic molecule. In contrast, sodium chloride (NaCl) is an ionic compound, formed when metal atoms lose one or more electrons to nonmetal atoms, producing cations and anions that are electrostatically attracted to each other.
