Question

# Write IUPAC names of the following:A.$[Co{(N{H_3})_5}Cl]C{l_2}$B.$[Pt{(N{H_3})_2}Cl(N{O_2})]$

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.

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$(II)$.
