Current Question (ID: 18672)

Question:

$\text{IUPAC name of } [\text{Pt} (\text{NH}_3)_3 (\text{Br})(\text{NO}_2)\text{Cl}]\text{Cl is:}$

Options:

1. $\text{Triamminebromidochloridonitroplatinum(IV)Chloride}$
2. $\text{Triamminebromonitrochloroplatinum(IV)Chloride}$
3. $\text{Triamminechlorobromonitroplatinum(IV)Chloride}$
4. $\text{Triamminenitrochlorobromoplatinum(IV)Chloride}$

Solution:

$\text{1. Ligands present inside the coordination sphere are: Br}^-\text{ (bromido), Cl}^-\text{ (Chlorido), NO}_2^-\text{ (nitro) and NH}_3\text{ (ammine). "tri" prefix will be used before ammine as three NH}_3\text{ ligands are present.}$ $\text{Ligands are named according to alphabetical order.}$ $\text{2. Let the oxidation state of Pt is "x"}$ $x + 3(0) + (-1) + (-1) = +1 \text{ (Because of one Cl}^- \text{ outside the sphere)}$ $x = +1 +3 = +4$ $\text{3. Thus, the IUPAC name of } [\text{Pt} (\text{NH}_3)_3 (\text{Br})(\text{NO}_2)\text{Cl}]\text{Cl is triamminebromidochloridonitroplatinum(IV)Chloride}$
