Match the chlorine oxoanion (List I) with its name (List II). List I: P $ClO X^{-}$ , Q $ClO X_{2} X^{-}$ , R $ClO X_{3} X^{-}$ , S $ClO X_{4} X^{-}$ . List II: 1 chlorate, 2 perchlorate, 3 hypochlorite, 4 chlorite.

The anions follow the oxidation number of Cl:

+ 1

hypochlorite,

+ 3

chlorite,

+ 5

chlorate,

+ 7

perchlorate. So

ClO X^{-}

is 3,

ClO X_{2} X^{-}

is 4,

ClO X_{3} X^{-}

is 1 and

ClO X_{4} X^{-}

is 2.
