This is the trend in oxidation states of platinum characterized by XANES analyses and its binding energies in X-ray photoelectron spectra [13] , [26] . Use of carbon tetrachloride in determination of oil has been replaced by various other solvents, such as tetrachloroethylene. It is in “chlorate” so the oxidation number of oxygen is 2-. [9] Because it has no C–H bonds, carbon tetrachloride does not easily undergo free-radical reactions. Attend. Favorite Answer. In chemistry, a formal charge (FC) is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity. [20] However, since 1992[21] its atmospheric concentrations have been in decline for the reasons described above (see atmospheric concentration graphs in the gallery).
