1,1-Dichloroethane, also referred to as ethylene dichloride, is a transparent chemical compound with the molecular formula C2H4Cl2. This substance is known for its volatile and flammable nature. It belongs to the group of chlorinated hydrocarbons, specifically aliphatic halocarbons. Its mode of action is akin to that of other halocarbons. Upon exposure to light, 1,1-Dichloroethane undergoes a photochemical reaction, resulting in the dissociation of chlorine atoms from the molecule. This process generates free radicals, which can engage in chemical reactions with other molecules, leading to the formation of novel compounds.
