Question

$Fe^{3 +}$ compounds are more stable than $Fe^{2 +}$ compounds because

A

$Fe^{3 +}$ has smaller size than $Fe^{2 +}$

B

$Fe^{3 +}$ has $3d^{5}$ configuration (half filled)

C

$Fe^{3 +}$ has higher oxidation state

D

$Fe^{3 +}$ is paramagnetic in nature

Answer

$Fe^{3 +}$ has $3d^{5}$ configuration (half filled)

Explanation

Solution

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