Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. The oxidation number represents the number of electrons Cl loses. The boxes enclose electrons assigned to a given atom by the rules for determining oxidation number. The oxiding power of HClO4, HClO3, HCLO2, HClO are in the order HClO >HCLO2 >HClO3>HClO4 because the oxidising states of chlorine in HClO4, HClO3, HCLO2, HClO are 7,5,3,1 respectively so HClO with lowest oxidation state of chlorine have greatest tendency to get oxidised and increase its oxidation state. The alkali metals (group I) always have an oxidation number of +1. Write the electron configuration of chlorine and explain why these are limiting oxidation numbers for chlorine. Weaker acids have higher oxidation numbers. Oxygen almost always keeps an oxidation number of -2. In both acid the oxidation number of chlorine and bromine are same ,that is +3 . The oxiding power of HClO4, HClO3, HCLO2, HClO are in the order HClO >HCLO2 >HClO3>HClO4 because the oxidising states of chlorine in HClO4, HClO3, HCLO2, HClO are 7,5,3,1 respectively so HClO with lowest oxidation state of chlorine have greatest tendency to get oxidised and increase its oxidation state. 3 × -2 = -6.
