Question

# Of the given anions, the strongest Bronsted base is:

A
ClO
B
ClO2
C
ClO3
D
ClO4

Solution

## The correct option is C $$ClO^{\circleddash}$$The Bronsted base is the substance that can accept  $$H^+$$.$$Oxidation\ state\ of\ the\ central\ atom\ \uparrow, Acidity \uparrow$$Thus the order of acidic strength of the conjugate acid would be:$$HClO< HCl{ O }_2 < HCl{ O }_3 < HCl{ O }_4$$Weaker the conjugate acid stronger the conjugate base.In the given conjugate bases the order of base strength is :$$ClO^-> Cl{ O }_2^-> Cl{ O }_3^->Cl{ O }_4^-$$ Hence, the correct option is A.  Chemistry
