Strongest conjugate base is
Options
- AClO ⁻
- BClO ₂⁻
- CClO ₃ ⁻
- DClO ₄⁻
Correct answer
A. ClO ⁻
Step-by-step solution
If acid is weak, its conjugate base is strong. Greater the oxidation number of Cl , stronger the acid and thus, weaker the conjugate base. aligned & HClO HClO ₂ HClO ₃ HClO ₄ aligned Oxidation number of Cl and acid strength increases ClO ⁻ ClO ₂⁻ ClO ₃⁻ ClO ₄⁻ Conjugate base strength increases. Hence, ClO ⁻ is the strongest base.
