The pka of oxoacids of chlorine in water follows the order

Question

The pka of oxoacids of chlorine in water follows the order (A) HClO < HClO3 < HClO2 < HClO4 (B) HClO4 < HClO3 < HClO2 < HClO (C) HClO4 < HClO2 < HClO3 < HClO (D) HClO2 < HClO < HClO3 < HClO4

pKa value of an acid is inversely proportional to acidic strength, i.e. stronger is the acid, lesser will be its pKa value. Also, the acidic strength increases with increase in the oxidation number of central atom. The oxidation number of central atom in given acids are given below. Acid Oxidation Number o f central atom HCIO +1 HClO3 +5 HClO2 +3 HClO4 +7 The acidic strength follows the order, HClO < HClO2 < HClO3 < HClO4 Thus, the pKa of oxoacids of chlorine in water, HClO4 < HClO3 < HClO2 < HClO

Q. The $p k_{a}$ of oxoacids of chlorine in water follows the order

$H ClO < H Cl O_{3} < H Cl O_{2} < H Cl O_{4}$

$H Cl O_{4} < H Cl O_{3} < H Cl O_{2} < H ClO$

$H Cl O_{4} < H Cl O_{2} < H Cl O_{3} < H ClO$

$H Cl O_{2} < H ClO < H Cl O_{3} < H Cl O_{4}$

Q. The pka​ of oxoacids of chlorine in water follows the order

HClO<HClO3​<HClO2​<HClO4​

HClO4​<HClO3​<HClO2​<HClO

HClO4​<HClO2​<HClO3​<HClO

HClO2​<HClO<HClO3​<HClO4​

Q. The $p k_{a}$ of oxoacids of chlorine in water follows the order

$H ClO < H Cl O_{3} < H Cl O_{2} < H Cl O_{4}$

$H Cl O_{4} < H Cl O_{3} < H Cl O_{2} < H ClO$

$H Cl O_{4} < H Cl O_{2} < H Cl O_{3} < H ClO$

$H Cl O_{2} < H ClO < H Cl O_{3} < H Cl O_{4}$
