Which statements are correct for ozone? — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: For oxyacids with the central atom in the same oxidation state, acidic strength increases with the electronegativity of the central halogen atom. Step 2: Since chlorine is more electronegative than bromine, and bromine is more electronegative than iodine, the correct order of acidic strength for perhalic acids is HClO4 > HBrO4 > HIO4. Step 3: Therefore, the order HIO4 > HBrO4 > HClO4 in option (b) is incorrect, making (b) the correct option.
