Question

Which of the following is true of the ascending order of acidicness in oxoacids?
A) HOCLO<HOCL<HOCLO3<HOCLO2
B) HOCLO2<HOCLO3<HOCLO<HOCL
C) HOCLO3<HOCLO2<HOCLO<HOCL
D) HOCL<HOCLO<HOCLO2<HOCLO3​

Answer 1

Answer:

A) HOCLO<HOCL<HOCLO3<HOCLO2

Answer 2

Answer:

A) HOCLO<HOCL<HOCLO3<HOCLO2

Explanation:

Oxygen is more electronegative than chlorine, therefore, dispersal of negative charge present on chlorine increases from ClO- to Cl4-

ion because number of oxygen atoms attached to chlorine is increasing. Therefore, stability of ions will increase in the order given below:

ClO - <ClO2− <ClO3− <ClO4−

This is due to increase in stability of conjugate base, acidic strength of corresponding acid increases in the following order:

HClO <HClO2 <HClO3<HClO4.
