Arrange the oxoacids of chlorine in the order of increasing acidic strength and explain the orders.

Explanation

Acidic strength: With increase in the number of oxygen in the conjugate base of the oxoacid, their resonance stabilization increases. Therefore, the order of increasing stability of the conjugate base: `CIO^(-) lt CIO_(2)^(-) lt CIO_(3)^(-) lt CIO_(4)`. Consequently, with increase in stability of the conjugate base, the acidic strength of the oxoacids increases in the order:
`HClO lt HCIO_(2) lt HClO_(3) lt HClO_(4)`
