Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R.Assertion A: The spin only magnetic moment value for $\displaystyle \left[\mathrm{Fe}(\mathrm{CN})_6\right]^{3-}$ is $\displaystyle 1.74$ BM , whereas for $\displaystyle \left[\mathrm{Fe}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{3+}$ is $\displaystyle 5.92$ BM.Reason R : In both complexes, Fe is present in +$\displaystyle 3$ oxidation state.
In the light of the above statements, choose the correct answer from the options given below:
Official answer
From NTA’s final answer key for this paper.
(2)
Both $\displaystyle A$ and $\displaystyle R$ are true but $\displaystyle R$ is NOT the correct explanation of $\displaystyle A$
