Question

Identify the species in which the metal atom is in +6 oxidation state.

• A. $Mn{O}_4^{-}$
• B. $Cr\left(CN\right)6{]}^{3-}$
• C. $Ni{F}_6^{2-}$
• D. $Cr{O}_{2}C{l}_2$

Answer 1

The correct option is D $Cr{O}_{2}C{l}_2$

Let the oxidation state of central metal atom $Cr$ be $X$.

then,$X+2(-2)+2(-1)=0$

$X=4+2$

$X=6$

$Cr{O}_{2}C{l}_2$ is the species in which the central metal atom in to oxidation state.
