Rank the following in order of increasingly positive hydrogen charge: a) HClO2, HCl, CH4, H2O, HClO

CH4<HClO2<HClO<H2O<HCl

Explanation:

In ranking the compounds on the basis of increasing positive charge of hydrogen, we must consider the relative oxidation numbers of the various elements in the compounds.

Methane contains a nonpolar covalent bond, HClO2 contains a chlorine atom in +3 oxidation state, HClO contains a chlorine atom in +1 oxidation state. The more the positive charge on the halogen atom the lesser the magnitude of positive charge on the hydrogen atom. Between water and HCl, chlorine is more electro negative hence HCl will contain a more positively charged hydrogen atom than water.
