Both carbon tetrachloride, CC1, (used in dry cleaning and in some lire extinguishers) and mercury, Hg, are liquids whose vapors are poisonous to breathe. If CCh is spilled, the danger can be removed merely by airing the room overnight but if mercury is spilled, it is necessary to pick up the liquid droplets with a vacuum cleaner device. Explain. 

The mechanism of carbon tetrachloride hepatotoxicity generally is viewed as an example of lethal cleavage, where the CCh— Cl bond is split in the mixed-function oxidase system of the hepatocytes. After this cleavage damage may occur directly from the free radicals (-CCl and -Cl) and/or from the formation of toxic metabolites such as phosgene." ...

The hexachloroethane is assumed to arise by the combination of CC13 radicals and the carbon tetrachloride by the abstraction of a chlorine atom from the hexachloroacetone by the CCh radicals. 

The same relation of reactivity and stability to periodic position is exhibited by such other carbon halides as hexachloroethane CCh CCU and hexabrumoclhane. Brj CBr.i. as well as by hexachloroethylene. CCU -CCI and Itexabromoethylene, CBr = CBr . Carbon also forms halides containing more than one halogen, See also Carbon Tetrachloride. 

Carbon Tetrachloride. The rapid decrease in G(H2)W upon adding 0.13 mole % CCh to water vapor containing 1 mole % isopropyl alcohol, followed by a slower fall-off as the CC14 concentration increases, is indicative of more than one precursor of hydrogen reacting with CC14. These may be identified as the electron and H atom, in view of their known reaction with CC14 in the vapor phase (II, 26)... 

Tn the y radiolysis of glasses of carbon tetrachloride containing various solutes, the positive ions of these solutes are formed by electron transfer to the positive ion of the host, (CCh) (10). Recent experiments in the y irradiation at 20 °K. of 3-methylpentane glasses with 1 mole % of CCI4 show that the species Cl2 is formed (5). No evidence of the positive ion of carbon tetrachloride with an absorption maximum at 4800 A. was obtained at 20°K., although this species is observed at higher temperatures (5,12). 

The dielectric medium is normally taken to have a constant value of e, but may for some purposes also be taken to depend for example on the distance from M. For dynamical phenomena it can also be allowed to be frequency dependent, i.e. the response of the solvent is different for a fast reaction, such as an electronic transition, and a slow reaction, such as a molecular reorientation. It should be noted that e is the only parameter characterizing the solvent, and solvents having the same value (such as acetone, e = 20.7, and 1-propanol, e = 20.1, or benzene, e = 2.28, and carbon tetrachloride, e = 2.24) are thus treated equally. The hydrogen bonding capability of 1-propanol compared with acetone will in reality most likely make a difference, and the solvent dynamics of an almost spherical CCh will be different from the planar benzene molecule. 

Reaction with Carbon Tetrachioride. Severe accidents have been caused by the rapid reaction of aluminum with anhydrous chlorinated solvents, such as in the degreasing of castings, in ball miUmg of aluminum flake with carbon tetrachloride (CCI4), or even in the case of aluminum used as a container at room temperature for mixed chlorinated solvents. The reaction with CCh, for example, has been shown to be...
