A) \[MnO_{4}^{-}\]
B) \[Cr(CN)_{6}^{3-}\]
C) \[NiF_{6}^{2-}\]
D) \[Cr{{O}_{2}}C{{l}_{2}}\]
Correct Answer: D
Solution :
\[MnO_{4}^{-}=x+(-2\times 4)=-1\] \[x-8=-1\] \[x=7\] \[Cr(CN)_{6}^{3-}=x+(-1\times 6)=-3\] \[x-6=-3\] \[x=+3\] \[NiF_{6}^{2-}=x+(-1\times 6)=-2\] \[x-6=-2\] \[x=4\] \[Cr{{O}_{2}}C{{l}_{2}}=x+(-2\times 2)+(-1\times 2)=0\] \[x-4-2=0\] \[x-6=0\] \[x=6\]You need to login to perform this action.
