The correct IUPAC name for the compound [Co(NH3)4CI(ONO)]Cl is
Show answer and solution
Cation is named first followed by anion. In coordination sphere
the ligands are named alphabetically followed by name of metal ion and
then its oxidation state in Roman numeral.
In [Co(NH3)4Cl(ONO)]+Cl-, cobalt is in +3 oxidation state and the
complex is cationic. ONO ligands attach to metal ion through O atom;
so --O-- is used while naming as nitrito before the name of metal
ion. So IUPAC name given in option (D) is correct.
