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 but R is the correct expanation of A
B. Both A and R are true but R is NOT the correct expanation of A
C. A is true but R is false
D. A is false and R is true

Answer

B

Explanation

In the complexes, Co exists as `Co^(2+)` and Fe as `Fe^(2+)`. Both of the complexes become Stable by oxidation of metal ion to `Co^(3+)` and `Fe^(3+)`.
