1.	The correct order of `E_(M^(2+)//M)^(@)` Values with negative sign for the four successive elements `Cr, Mn, Fe` and `Co` is:A. `MngtCrgtFegtCo`B. `CrgtFegtMngtCo`C. `FegtMngtCrgtCo`D. `CrgtMngtFegtCo`
Answer» Correct Answer - 1 Generally across the first transition series, the negative value for standard electrode potential decrease (exception `Mn`-due to stable `d^(5)` configuration) Standard electrode potential- `{:(,Mn,Cr,Fe,Co,),(M^(2+)//M,-1.18,-0.90,-0.44,-0.28,eV):}` So, correct order is `MngtCrgtFegtCo.`
