Of the given anions, the strongest Bronsted base is
A.
$$CI{O^ - }$$
B.
$$CIO_2^ - $$
C.
$$CIO_3^ - $$
D.
$$CIO_4^ - $$
Answer :
$$CI{O^ - }$$
Solution :
TIPS/Formulae :
(i) Lower the oxidation state of central atom, weaker will be oxy acid.
(ii) Weaker the acid, stronger will be its conjugate base.
Oxidation state of $$Cl$$ in $$HClO$$ is + 1, in $$HCl{O_2}$$ is + 3, in $$HCl{O_3}$$ is + 5, and in $$HCl{O_4}$$ is + 7
∴ $$HClO$$ is the weakest acid and so its conjugate base $$Cl{O^ - }$$ is the strongest Bronsted base.
