Inorganic molecules are compounds that typically do not contain carbon-hydrogen (C-H) bonds. They can be composed of various elements, including metals, nonmetals, and metalloids. Common examples of inorganic molecules include water (H₂O), salts like sodium chloride (NaCl), and acids such as hydrochloric acid (HCl). These molecules play essential roles in various chemical processes and are fundamental to many biological systems. Inorganic molecules are often categorized into different groups, such as oxides, sulfides, and halides. They can be found in nature and are used in various industries, including agriculture, manufacturing, and pharmaceuticals. Understanding inorganic molecules is crucial for fields like chemistry and materials science, as they form the basis for many chemical reactions and materials.
