Vedclass · Answer

(C) In $CrO_4^{2-}$ (chromate ion),the central $Cr$ atom is $sp^3$ hybridized,and due to resonance,all four $Cr-O$ bonds are equivalent.In $MnO_4^{-}$ (permanganate ion),the central $Mn$ atom is $sp^3$ hybridized,and due to resonance,all four $Mn-O$ bonds are equivalent.In $Cr_2O_7^{2-}$ (dichromate ion),there is a bridging $Cr-O-Cr$ bond and terminal $Cr=O$ bonds,which are not all equivalent.Therefore,only $I$ and $II$ contain all equivalent $M-O$ bonds.

The oxoanion which contains all equivalent $M-O$ bonds is:
$(I)$ $CrO_4^{2-}$
$(II)$ $MnO_4^{-}$
$(III)$ $Cr_2O_7^{2-}$
