Current Question (ID: 18686)

Question:
$\text{The correct IUPAC name for } [\text{Pt} (\text{en})_2 \text{Cl(ONO)}]^{2+} \text{ is:}$
Options:
  • 1. $\text{Chlorodiethylenediaminenitritoplatinum(IV) ion}$
  • 2. $\text{Bis(ethylenediamine)chloronitro-O-platinum(IV) ion}$
  • 3. $\text{Chloridobis(ethylenediamine)nitritoplatinum(IV) ion}$
  • 4. $\text{Chlorodiethylenediaminenitro-O-platinum(IV) ion}$
Solution:
$\text{The given complex is } [\text{Pt} (\text{en})_2 \text{Cl(ONO)}]^{2+}.$ $\text{1. In the complex, Cl, en, and ONO are the ligands. For Cl ligand chlorido is used, for en "ethylenediamine" is used.}$ $\text{In the given complex 2 en molecules are present, hence bis are used. for ONO nitrito is used.}$ $\text{2. Let oxidation number of Pt is "x"}$ $x + (-1) + (-1) = +2$ $x = +4$ $\text{Thus, the oxidation state of platinum is +4.}$ $\text{STEP 3: The IUPAC name of the compound is Chloridobis(ethylenediamine)nitritoplatinum(IV) ion.}$
