Ncert Exercises & Solutions

Assertion (A):	$[C r (H_{2} O_{6})] C l_{2}$ and $[F e {(H_{2} O)}_{6}] C l_{2}$ are reducing in nature.
Reason (R):	Unpaired electrons are present in their d-orbitals.

1.	Both (A) and (R) are True and the (R) is the correct explanation of (A).
2.	Both (A) and (R) are True and (R) is not the correct explanation of (A).
3.	(A) is true but the (R) is False.
4.	(A) is False but (R) is True.

Hint: Both can show a +3 oxidation state

Assertion and reason both are true but the reason is not correct explanation for the assertion.

[C r (H_{2} O_{6})] C l_{2}

and

[F e {(H_{2} O)}_{6}] C l_{2}

are reducing in nature due to formation of more stable complex ion after gaining of electron.
