The hypothesis regarding long-living halogen compounds, such as chlorofluorocarbons (CFCs) and halons, posits that these substances can deplete the ozone layer. When released into the atmosphere, these compounds can persist for years and eventually reach the stratosphere, where they are broken down by ultraviolet (UV) radiation, releasing chlorine and bromine atoms. These halogen atoms then catalyze reactions that lead to the destruction of ozone (O3) molecules, significantly reducing the ozone layer's ability to absorb harmful UV radiation. This process contributes to increased UV exposure at the Earth's surface, leading to various environmental and health issues.
There are various chemical pollutants responsible. These pollutants are the halogen compounds of carbon.
Br2 is a halogen that can be prepared only from its fused compounds.
Examples of inter-halogen compounds are chlorine trifluoride (ClF3), iodine pentafluoride (IF5), and bromine chloride (BrCl). These compounds are formed by the combination of different halogen elements, such as chlorine, fluorine, iodine, and bromine.
No, magnesium is not a halogen. It is a metal element. However, magnesium can form compounds with carbon, known as organomagnesium compounds or Grignard reagents, which are commonly used in organic synthesis.

A halogen carrier is a compound that helps facilitate halogenation reactions by carrying or transferring halogen atoms to other molecules. This process is commonly used in organic chemistry to introduce halogen atoms (such as chlorine, bromine, or iodine) into organic compounds. Common examples of halogen carriers include N-chlorosuccinimide (NCS) and N-bromosuccinimide (NBS).
Iodine is a halogen that can appear violet in its elemental form or as certain compounds.
Ions of the halogen group are called halide ions; their compounds are called halides.
Interhalogen compounds are molecules composed of two different halogen atoms bonded together. They exhibit intermediate properties between those of the two halogen elements involved in the compound. Examples include chlorine monofluoride (ClF) and iodine pentafluoride (IF5).
Halogen compounds are commonly used as disinfectants, bleaching agents, and in the production of pharmaceuticals and plastics. They are also used in water treatment, as flame retardants, and in the manufacturing of electronic components.
