stratospheric phenomena of Earth

Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F). They are produced as volatile derivatives of methane, ethane, and propane.

Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula . This colorless, volatile liquid with a chloroform-like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar and miscible with many organic solvents.

Halothane (bromochlorotrifluoroethane), sold under the brand name Fluothane among others, is a halocarbon with the chemical formula . It is used as a general anaesthetic given by inhalation. It can be used to induce or maintain anaesthesia. Its use in developed countries has been mostly replaced by newer anesthetic agents such as sevoflurane. One of its benefits is that it does not increase the production of saliva, which can be particularly useful in those who are difficult to intubate.
