The correct order of acid strength is

• HClO < HClO₂ < HClO₃ < HClO₄

• HClO₄ < HClO < HClO₂ < HClO₃

• HClO₂ < HClO₃ < HClO₄ < HClO

• HClO₄ < HClO₃ < HClO₂ < HClO

32.

The main reason for larger number of oxidation states exhibited by the actinides than the corresponding lanthanides, is

• lesser energy difference between 5f and 6d orbitals than between 4f and 5d orbitals

• larger atomic size of actinides than the lanthanide

• more energy difference between 5f and 6d orbitals than between 4f and 5d orbitals

• greater reactive nature of the actinides than the lanthanides
