Which term describes something unrelated to organic matter or organic life, or a chemical compound that does not contain carbon?

• A. Inorganic
• B. Organic
• C. Metallic
• D. Alloy

Answer: (A)

Substances are classified as inorganic when they are not based on carbon-hydrogen frameworks or are not tied to living organisms. Organic compounds, by contrast, contain carbon-hydrogen bonds and are typically associated with living matter or their derivatives. The description here points to inorganic because it refers to things unrelated to organic matter or life, or a chemical that does not contain carbon. While some carbon-containing species like carbon dioxide or carbonates are considered inorganic in practice, the general rule is that anything without the characteristic carbon-hydrogen backbone falls under inorganic. The other terms don’t fit because organic denotes carbon-containing compounds, and metallic or alloy describe material types rather than the carbon-based classification of compounds.
