Vedclass · Answer

(D) To determine if a complex is paramagnetic,we check for the presence of unpaired electrons in the central metal ion.$1$. In $[Fe(CN)_6]^{4-}$,$Fe$ is in $+2$ oxidation state $(d^6)$. $CN^-$ is a strong field ligand,causing pairing of electrons,resulting in $0$ unpaired electrons (diamagnetic).$2$. In $[Cu(NH_3)_4]^{2+}$,$Cu$ is in $+2$ oxidation state $(d^9)$. It has $1$ unpaired electron in the $3d$ orbital (paramagnetic).$3$. In $[Ti(H_2O)_6]^{3+}$,$Ti$ is in $+3$ oxidation state $(d^1)$. It has $1$ unpaired electron in the $3d$ orbital (paramagnetic).Therefore,both $[Cu(NH_3)_4]^{2+}$ and $[Ti(H_2O)_6]^{3+}$ are paramagnetic.
