JEE Main 2023 — Coordination Compounds Question with Solution

Given below are two statements, one is labelled as Assertion $$\mathbf{A}$$ and the other is labelled as Reason $$\mathbf{R}$$.

Assertion A: The spin only magnetic moment value for $${\left[\mathrm{Fe}(\mathrm{CN}{)}_6\right]}^{3-}$$ is $$1.74\mathrm{BM}$$, whereas for $${\left[\mathrm{Fe}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{3+}$$ is $$5.92\mathrm{BM}$$.

Reason $$\mathbf{R}$$ : In both complexes, $$\mathrm{Fe}$$ is present in +3 oxidation state.

In the light of the above statements, choose the correct answer from the options given below:
