' X ' is the number of electrons in t_ 2 g orbitals of the most stable complex ion among [ Fe ( NH ₃ )₆ ]³⁺ , [ Fe ( Cl ₆ ) ]³⁻, [ Fe ( C ₂ O ₄ )₃ ]³⁻ and [ Fe ( H ₂ O )₆ ]³⁺ . The nature of oxide of vanadium of the type V ₂ O _ X is:

Options

  1. AAcidic
  2. BNeutral
  3. CBasic
  4. DAmphoteric

Correct answer

D. Amphoteric

Step-by-step solution

Most stable is [ Fe ( C ₂ O ₄ )₃ ]³⁻ due to Chelation effect. V ₂ O ₅ is amphoteric.
