The acidic nature of the oxoacids of chlorine is
`HOCl ltHClO_(2)ltHClO_(3)ltHClO_(4)-"explain."`
(Hint : `HA+H_(2)O iff H_(3)O^(+)+A^(-)` conjugate base, greater the stability of `A^(-)`, lesser will be its basic strength or greater will be the tendency of HA to release `H^(+)`. In other words, stronger will be the acid HA. Among the conjugate bases of oxoacids of chlorine, the stability order is `"H OCl"^(-)lt ClO_(2)^(-) gt ClO_(3)^(-) gtClO_(4)^(-)`

Explanation

Given the acidic nature of oxoacids of chlorine is
`HOCl^(-)ltHClO_(2)^(-)gtHClO_(3)^(-)gtHClO_(4)^(-)`
`HA+H_(2)O iffH_(3)O^(+)+A^(-)` conjugate base, greater the stability of `A^(-)`, lesser will be its basic strength or greater will be the tendency of HA to release `H^(+)` . In other words, stronger will be the acid HA. Among the conjugate bases of oxoacids of chlorine, the stability order is `HOCl^(-)ltHClO_(2)^(-) gtHClO_(3)^(-)gtHClO_(4)^(-)`
