Step-by-step solution
In the naming of complex ion ligands are named first alphabatically followed by name of metal ion along with its oxidation number. the ligands are Amine and Chloride. Since there are 4 amine groups we’ll name it as tetramine and 2 chloride groups will be named as dichloro. Also, we have platinum metal as the central metal atom in a cation, and it’s oxidation state is + 4 . Now for the other (anionic part): Here the ligand is chloride. Since there are 4 chlorides so we’ll call it tetrachloride . We have the central
