D and F Block Elements question

2008 · Shift 0 · Q20

JEE MainChemistryD and F Block ElementsMCQ+4 / −1
Larger number of oxidation states are exhibited by the actinoids than those by the lanthanoids, the main reason being :
  1. A
    4f orbitals more diffused than the 5f orbitals
  2. B
    lesser energy difference between 5f and 6d than between 4f and 5d orbitals
  3. C
    more energy difference between 5f and 6d than between 4f and 5d orbitals
  4. D
    more reactive nature of the actinoids than the lanthanoids
