Vedclass · Answer

(C) For Manganate ion $(MnO_4^{2-})$: $1$. It has a tetrahedral structure. $2$. $p\pi-d\pi$ bonding is present between $Mn$ and $O$. $3$. It is paramagnetic due to the presence of one unpaired $d$-electron in $Mn^{+6}$ $(3d^1)$. For Permanganate ion $(MnO_4^{-})$: $1$. It has a tetrahedral structure. $2$. $p\pi-d\pi$ bonding is present between $Mn$ and $O$. $3$. It is diamagnetic due to the absence of unpaired $d$-electrons in $Mn^{+7}$ $(3d^0)$. $4$. It is a stronger oxidising agent than manganate. Comparing these,statement $C$ is incorrect because manganate is paramagnetic while permanganate is diamagnetic.
