A compound which does not contain carbon is known as:

A compound that does not contain carbon is classified as inorganic. Inorganic compounds typically encompass a wide range of substances, including minerals, metals, and salts. They can be found in nature and are not primarily derived from living organisms, which differentiates them from organic compounds.

Organic compounds are characterized by the presence of carbon atoms and are often associated with biological systems. Biochemical refers to substances produced by living organisms, which also predominantly involve carbon-containing compounds. Hydrocarbons, as the name suggests, consist specifically of hydrogen and carbon atoms and thus do not fit the definition of a compound lacking carbon.

In summary, inorganic is the correct classification for a compound that does not contain carbon, highlighting the distinction between carbon-based organic compounds and those that are not.
