(a) Determine the formal charge on the chlorine atom in the hypochlorite ion, ClO-, and the perchlorate ion, ClO4-, using resonance structures where the Cl atom has an octet.
(b) What are the oxidation numbers of chlorine in ClO- and in ClO4-?
(c) Is it uncommon for the formal charge and the oxidation state to be different? Explain.
(d) Perchlorate is a much stronger oxidizing agent than hypochlorite. Would you expect there to be any relationship between the oxidizing power of the oxyanion and either the oxidation state or the formal charge of chlorine
