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

Options

  1. Alesser energy difference between 5f5 f and 6d6 d orbitals than between 4f4 f and 5d5 d orbitals
  2. Blarger atomic size of actinides than the lanthanide
  3. Cmore energy difference between 5f5 f and 6d6 d orbitals than between 4f4 f and 5d5 d orbitals
  4. Dgreater reactive nature of the actinides than the lanthanides

Correct answer

A. lesser energy difference between 5f5 f and 6d6 d orbitals than between 4f4 f and 5d5 d orbitals

Step-by-step solution

The main reason for larger number of oxidation states exhibited by actinides than corresponding lanthanides is lesser energy difference between 5f5 f and 6d6 d orbitals than between 4f4 f and 5d-orbitals.
