Assertion (A) : `[Cr(H_(2)O)_(6)]Cl_(2) and [Fe(H_(2)O)_(6)]Cl_(2)` are reducing in nature.
Reason (R) : Unpaired electrons are present in their d - orbitals.

Options

A. Both (A) and (R) are true and (R) is the correct explanation of (A)
B. Both (A) and (R) are true but (R) is not the correct explanation of (A)
C. (A) is true but (R) is false
D. (A) is false but (R) is true

Answer

B

Explanation

Actual reason : `Cr^(2+)(3d^(4)) and Fe^(2+)(3d^(6))` can undergo oxidation to `Cr^(3+)(3d^(3)) and Fe^(3+)(3d^(5))` respectively.
