Vedclass · Answer

(A) The complex $Ba[CuCl_4]$ consists of a barium cation $Ba^{2+}$ and a complex anion $[CuCl_4]^{2-}$.In the anion $[CuCl_4]^{2-}$,let the oxidation state of $Cu$ be $x$.$x + 4(-1) = -2$,which gives $x = +2$.Thus,the oxidation state of copper is $(II)$.According to $IUPAC$ nomenclature,the cation is named first,followed by the anion.The ligand $Cl^-$ is named as 'chloro' and since there are four,it is 'tetrachloro'.Since the complex is an anion,the metal name ends in '-ate',so 'copper' becomes 'cuprate'.Therefore,the $IUPAC$ name is barium tetrachlorocuprate $(II)$.
