Assertion : the oxidation numbers are artificial , they are useful as a ‘book – keeping ‘ device of electrons in reactions. Reason : THe oxidation numbers do not usually represent real charges on atoms , they are simply conventions that indicate what the maximum charge could possibly be on an atom in a molecule.
