(a) Explain why [ Fe ( H_2 O )_6]^3+ is strongly paramagnetic whereas [ Fe ( CN )_6]^3- is weakly paramagnetic. [Atomic number of Fe =26 ] 2 + 1 (b)…

Explain why $\displaystyle \left[\mathrm{Fe}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{3+}$ is strongly paramagnetic whereas $\displaystyle \left[\mathrm{Fe}(\mathrm{CN})_{6}\right]^{3-}$ is weakly paramagnetic. [Atomic number of $\displaystyle \mathrm{Fe}=26$ ] $\displaystyle \mathbf{2} \boldsymbol{+} \mathbf{1}$

On the basis of crystal field theory, write the electronic configuration for $\displaystyle \mathrm{d}^{5}$ ion for which $\displaystyle \Delta_{0}<\mathrm{P}$.
