What does inorganic chemistry study?

Inorganic chemistry focuses on the study of the elements and their compounds that do not primarily contain carbon-hydrogen bonds. This field encompasses a vast array of substances, including metals, minerals, and coordination compounds. Inorganic chemists are concerned with understanding the properties, structures, and behaviors of these compounds, which include everything from salts to transition metals and complex chemical systems.

The correct choice highlights that inorganic chemistry essentially excludes organic compounds, which are central to organic chemistry. By concentrating on elements and compounds that do not include carbon in the usual bonding contexts, inorganic chemistry allows for the exploration and understanding of a wide range of materials and their applications in fields such as materials science, catalysis, and medicine.
