Current Question (ID: 18674)

Question:

$\text{The complex } [\text{Pt (NH}_3)_2\text{Cl(NH}_2\text{CH}_3)]\text{Cl correct IUPAC name is:}$

Options:

1. $\text{Diamminechlorido(methylamine)platinum(II)chloride}$
2. $\text{Diamminechloro(aminomethyl)platinum(II)chlorido}$
3. $\text{Chlorodiammine(methylamine)platinate(II)chloride}$
4. $\text{Chlorido(methylamine)diammineplatinum(II)chloride}$

Solution:

$\text{HINT: CH}_3\text{NH}_2 \text{ and NH}_3 \text{ are neutral ligands.}$ $\text{Explanation:}$ $\text{STEP 1:}$ $\text{In the given complex } [\text{Pt(NH}_3)_2\text{Cl(NH}_2\text{CH}_3)]\text{Cl, CH}_3\text{NH}_2 \text{ and NH}_3 \text{ are the neutral ligands.}$ $\text{The oxidation number of Pt is } +2. \text{ For NH}_3, \text{ diammine is used, and for Cl chlorido.}$ $\text{For CH}_3\text{NH}_2 \text{ methylamine is used.}$ $\text{STEP 2:}$ $\text{Let, the oxidation number of Pt is } \text{''}x\text{''}$ $x + (-1) = +1$ $x = +2$ $\text{STEP 3: The IUPAC name of the complex is Diamminechlorido(methylamine)platinum(II)chloride.}$
