Vedclass · Answer

(D) The correct answer is $D$. $A$. $MnCl_4^{2-}$: $Mn$ is in $+2$ oxidation state $(d^5)$. $Cl^-$ is a weak field ligand,leading to $sp^3$ hybridization and tetrahedral geometry. It has $5$ unpaired electrons,so it is paramagnetic. This statement is true.$B$. $[Mn(CN)_6]^{2-}$: $Mn$ is in $+4$ oxidation state $(d^3)$. It forms an octahedral complex ($d^2sp^3$ or $sp^3d^2$). It has $3$ unpaired electrons,so it is paramagnetic. This statement is true.$C$. $[CuCl_4]^{2-}$: $Cu$ is in $+2$ oxidation state $(d^9)$. It is a tetrahedral complex ($sp^3$ hybridization). However,the statement claims square planar geometry,which is incorrect for $[CuCl_4]^{2-}$. Note: $[CuCl_4]^{2-}$ is actually tetrahedral. Wait,checking the options: $[Ni(PPh_3)_2Br_2]$ is a $4$-coordinate complex,which is tetrahedral,not trigonal bipyramidal. Thus,$D$ is definitely false.$D$. $[Ni(PPh_3)_2Br_2]$: $Ni$ is in $+2$ oxidation state $(d^8)$. It is a $4$-coordinate complex,which typically adopts tetrahedral geometry,not trigonal bipyramidal. Therefore,this statement is false.
