Vedclass · Answer

(D) The central metal is chromium in the $+3$ oxidation state. Ligands present are: two ammine $(NH_3)$ which are neutral,two chloro $(Cl^-)$ which have a charge of $-1$ each,and two cyano $(CN^-)$ which have a charge of $-1$ each. The total charge on the coordination entity is calculated as: $x + 2(0) + 2(-1) + 2(-1) = +3 + 0 - 2 - 2 = -1$. Therefore,the correct formula is $[CrCl_2(CN)_2(NH_3)_2]^-$.

The correct formula of diammine dichlorodicyano chromate $(III)$ is
