Step-by-step solution

CCl 4 is used as fire extinguishers under the name of pyrene. The dense vapours of carbon tetrachloride forms a protective layer on the burning objects and avoids the oxygen or air to come in contact with the fire from the burning objects and provides incombustible vapours. Chemical paint strippers that include methylene chloride and phenol have been extensively used to remove polymer coatings from metallic substrates. These strippers are inexpensive and remove polymeric organic coatings quickly and easily from a v
