What is the correct increasing order of Brønsted basic strength?
Show Hint
Higher oxidation state \(\Rightarrow\) weaker conjugate base.

- \(\text{ClO}_4^- < \text{ClO}_3^- < \text{ClO}_2^- < \text{ClO}^-\)
- \(\text{ClO}_4^- > \text{ClO}_3^- > \text{ClO}_2^- > \text{ClO}^-\)
- \(\text{ClO}_3^- < \text{ClO}_4^- < \text{ClO}_2^- < \text{ClO}^-\)
- \(\text{ClO}^- > \text{ClO}_3^- > \text{ClO}_2^- < \text{ClO}_4^-\)

The Correct Option is A
Solution and Explanation
Step 1: Brønsted base strength is inverse of acid strength.
Step 2: \(\text{HClO}_4\) is strongest acid, so \(\text{ClO}_4^-\) is weakest base.
Step 3: Basicity increases as oxidation state of chlorine decreases.
