Inorganic chemistry is the study of substances that do not contain carbon. As opposed to organic chemistry, which focuses on compounds containing carbon, inorganic chemistry includes the study of elements, minerals, metals, and compounds such as salts and oxides.

Therefore, it is important to understand the distinction between organic and inorganic chemistry to correctly answer this question.
