​'X' is the number of electrons in t2g orbitals of the most stable complex ion among [Fe(NH3)6]^(3+)​, [Fe(Cl6)]^(3-) and [Fe(H2O)6]^(3+)

Question

'X' is the number of electrons in \(t_{2g}\) orbitals of the most stable complex ion among \([Fe(NH_3)_6]^{3+} , \ [Fe(Cl_6)]^{3-} , \ [Fe(C_2O_4)_3]^{3-} \ \text{and } [Fe(H_2O)_6]^{3+}\) The nature of oxide of vanadium of the type \(V_2O_x\) is:

(1) Acidic

(2) Neutral

(3) Basic

(4) Amphoteric

Answer 1

Correct option is: (4) Amphoteric

Most stable is \([Fe(C_2O-4)_3]^{3-}\) due to Chelation effect.

\(Ve \ O_5\) is amphoteric.
