Molecules that lack the basic framework of carbon and hydrogen are described as what?

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

Answer: (D)

In chemistry, organic compounds are typically built around carbon and usually contain carbon–hydrogen bonds. If a molecule lacks that carbon–hydrogen framework, it’s categorized as inorganic. So describing molecules that do not have a C–H backbone as inorganic fits the common classification, since many inorganic substances (like water and salts) do not rely on carbon–hydrogen structures. The other terms don’t fit as well: organic implies a carbon–hydrogen framework; metallic refers to metallic bonding properties; biochemical denotes substances involved in living systems and is not the general label for non–C–H molecules.
