${\mathrm{H}}_2\mathrm{O}$ is WFL

(A) ${\left[\mathrm{Cr}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{3+}\to \mathrm{n}=3$

(B) ${\left[\mathrm{Fe}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{2+}\to \mathrm{n}=4\to$ Highest paramagnetic

(C) ${\left[\mathrm{Cu}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{2+}\to \mathrm{n}=1$

(D) ${\left[\mathrm{Zn}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{2+}\to \mathrm{n}=0$

No. of unpaired electron ↑ Paramagnetic nature ↑
