Question:
Strongest conjugate base is
Strongest conjugate base is
Show Hint
More resonance → weaker base.
Updated On: Apr 23, 2026
- ClO$^-$
- ClO$_2^-$
- ClO$_3^-$
- ClO$_4^-$
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Conjugate base strength $\propto$ inverse of acid strength
Step 1: More oxygen → stronger acid due to resonance.
Step 2: Acid strength order: \[ \text{HClO}_4>\text{HClO}_3>\text{HClO}_2>\text{HClO} \]
Step 3: Hence conjugate base strength: \[ \textcolor{red}{ClO}^->\text{ClO}_2^->\text{ClO}_3^->\text{ClO}_4^- \] Conclusion:
Strongest base = ClO$^-$
