Among the following, the correct order of acidity is :
HClO3 < HClO4 < HClO2 < HClO
HClO < HClO2 < HClO3 < HClO4
HClO2 < HClO < HClO3 < HClO4
HClO4 < HClO2 < HClO < HClO3
As we learned in concept no
Conjugate acid base pair -
If bronsted acid is a strong acid then its conjugate base is a weak base and vice versa.
- wherein
Cl- is conjugate base of HCl & H3O+ is conjugate acid of H2O.
The strength of an acid is directly proportional to the stability of its conjugate base
The stability order of conjugate bases is
because of delocalization extent of -ve charge
Option 1)
HClO3 < HClO4 < HClO2 < HClO
This option is incorrect
Option 2)
HClO < HClO2 < HClO3 < HClO4
This option is correct
Option 3)
HClO2 < HClO < HClO3 < HClO4
This option is incorrect
Option 4)
HClO4 < HClO2 < HClO < HClO3
This option is incorrect
