The rules for oxidation states (O.S.) +3, –2, +6, +5 First of all, when determining oxidation numbers, ignore the coefficients. This is particularly important in redox reactions where some atoms lose (are oxidised) and others gain (are reduced) electrons. Oxidation number is the charge left on the atom of interest, when all the bonding pairs of electrons are broken with the charge devolving to the most electronegative atom. The "aloneness" can be a bit confusing. Benzene topic. to give a total oxidation of 0 . C = +4. There are 7 O so this contributes an overall effect of -14. How does AlCl4- formed then?
