Write IUPAC names of the following:

Answer Verified Verified
Hint: At first think about the structure and formula of complex compounds and then try to remember the rules of IUPAC nomenclature for the complex compounds. The IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended by the International Union OF Pure and Applied Chemistry.

Complete step by step answer:
The following steps must be followed to write the IUPAC name of the coordination compounds:
-The name of the ligand and the metal ion must be first written.
-The neutral ligand must be written first, followed by the negative and lastly the positive one must be written.
-In the case of more than one ligand, alphabetical must be used.
-The suffix “-ido” must be added to the names of the anions.
-The central atom must be named and its oxidation number must be mentioned in the brackets.
Therefore, according to the above steps the IUPAC name of the compound $[Co{(N{H_3})_5}Cl]C{l_2}$ is pentaamminechlorocobalt$(III)$chloride, where the oxidation state of cobalt is three.
In the compound $[Pt{(N{H_3})_2}Cl(N{O_2})]$ the oxidation number of platinum is two. The IUPAC name of the compound $[Pt{(N{H_3})_2}Cl(N{O_2})]$ is diammine dichloride nitrito$ - N - $platinum$(II)$.
To name a coordination compound, no matter whether the complex ion is the cation or ion, always name the cation before the anion.

A complex is a substance in which a metal or ion is associated with a group of neutral molecules or ions called ligands. Coordination compounds are neutral substances in which at least one ion is present as complex.
