In 1910, the Pyrene Manufacturing Company of Delaware filed a patent to use carbon tetrachloride to extinguish fires. Carbon tetrachloride has a sweet odor, and most people can begin to smell it in air when concentration reaches 10 parts carbon tetrachloride per million parts of air (ppm). With the CAS registry number 56-23-5, it is also named as Kohlenstofftetrachlorid. At high temperatures in air, it decomposes or burns to produce poisonous phosgene.

Don't forget to draw in lone pairs where needed to give octets. It has practically no flammability at lower temperatures. Carbon tetrachloride (CCl 4) is a covalently bonded compound composed of a central carbon surrounded by 4 chlorine atoms in a tetrahedral structure. In 1992, production in the U.S./Europe/Japan was estimated at 720,000 tonnes. In the carbon tetrachloride molecule, four chlorine atoms are positioned symmetrically as corners in a tetrahedral configuration joined to a central carbon atom by single covalent bonds. However, these refrigerants play a role in ozone depletion and have been phased out. lone pair of electrons or nonbonded electron pair.
