Fe3+ compounds are more stable than Fe2+ compounds because

Question

Fe3+ compounds are more stable than Fe2+ compounds because (A) Fe3+ has smaller size than Fe2+ (B) Fe3+ has 3d5 configuration (half-filled) (C) Fe3+ has higher oxidation state (D) Fe3+ is paramagnetic in nature

Tardigrade Admin · Accepted Answer

3d5 configuration is more stable due to singly occupied half-filled orbitals.

Q. $F e^{3 +}$ compounds are more stable than $F e^{2 +}$ compounds because

$F e^{3 +}$ has smaller size than $F e^{2 +}$

$F e^{3 +}$ has $3 d^{5}$ configuration (half-filled)

$F e^{3 +}$ has higher oxidation state

$F e^{3 +}$ is paramagnetic in nature

$3 d^{5}$ configuration is more stable due to singly occupied half-filled orbitals.
