Tetrachloroethylene (perchloroethylene, PCE), is a chlorinated ethylene compound commonly used as a dry cleaning and degreasing solvent. Chem. J. It is used in neutrino detectors where a neutrino interacts with a neutron in the chlorine atom and converts it to a proton to form argon. Ethylene bromide (C 2 H 4 Br 2), also called ethylene dibromide or 1,2-dibromoethane, a colourless, sweet-smelling, nonflammable, toxic liquid belonging to the family of organohalogen compounds.Ethylene bromide was once used in conjunction with lead-containing antiknock agents as a component of gasoline; however, this use disappeared with the banning of leaded gasoline. To write Lewis dot structure I think you can get that but one hint is to put a double bond between the carbons. Because it is stored in the body's fat and slowly released into the bloodstream, tetrachloroethylene can be detected in the breath for weeks following a heavy exposure.
