Organohalides are organic compounds that contain at least one halogen atom, such as fluorine, chlorine, bromine, or iodine, bonded to a carbon atom. These compounds can be found in various forms, including gases, liquids, and solids, and are commonly used in industrial applications, such as solvents, pesticides, and pharmaceuticals. The presence of halogens in organohalides often affects their chemical properties, making them useful in many chemical reactions. However, some organohalides can be harmful to the environment and human health, leading to regulations on their use and disposal.
