I Oxidation states can be thought of as a counterpart of formal charge which assumes that all bonding is ionic, i.e. “shared” electrons belong to the more electronegative element.

Rules for assigning oxidation states 1. The sum of the oxidation states in a molecule is equal to the charge. 2. In a bond between two identical atoms, the electrons are equally shared. 3. In any other bond, we “give” all the shared electrons to the more electronegative atom. 4. oxidation state = valence electrons of neutral atom - electrons in ionized structure

Oxidation states of chlorine in its oxoanions ClO - ClO - 2 ClO - 3 ClO - 4 Oxidation state of Cl: +1 +3 +5 +7 In most compounds, chlorine has an oxidation state of - 1. In Cl 2 , chlorine has an oxidation state of 0. The oxoanions (and their acids) are farther from the preferred oxidation state of chlorine and therefore better oxidizing agents than chlorine itself.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
