Question
Consider the oxoacids of Chlorine: $HClO, HClO_2, HClO_3, HClO_4$. What is the correct increasing order of their acidic strength?
Answer: B
💡 Solution & Explanation
Acidic strength of oxoacids with the same central atom increases with its positive oxidation state. Higher oxidation state ($+7$ in $HClO_4$) means higher effective electronegativity, weakening the O-H bond.
