Vedclass · Answer

(B) $(i)$ Manganese exhibits $+7$ oxidation state in its oxide,$Mn_2O_7$. This is a correct statement.$(ii)$ Ruthenium $(Ru)$ and Osmium $(Os)$ exhibit $+8$ oxidation state in their oxides,$RuO_4$ and $OsO_4$. This is a correct statement.$(iii)$ Scandium $(Sc)$ has an electronic configuration of $[Ar] 3d^1 4s^2$ and shows only $+3$ oxidation state. It does not show $+4$ oxidation state. This is an incorrect statement.$(iv)$ Chromium $(Cr)$ in its $+6$ oxidation state (e.g.,in $Cr_2O_7^{2-}$) acts as a strong oxidizing agent. This is a correct statement.Therefore,the correct statements are $(i), (ii)$ and $(iv)$.
