The IUPAC name of \([Pt(NH_3)_2Cl_2]\) is:

Diammine dichlorido platinum (II)

The correct answer is option 1: Diammine dichlorido platinum (II).

DLP

The correct IUPAC name for [Pt(NH3)2Cl2] is: (1) Diammine dichlorido platinum (II)

Here is why:

Central metal: Platinum \((Pt)\.

Ligands: Ammonia \((NH_3)\) and Chlorine \((Cl)\)

Oxidation state of Pt: \(+2\) (determined by balancing the charges of the ligands)

Number of ligands: Two each of \(NH_3\) and \(Cl\)

Overall charge: Neutral (no additional charge indicated)

Therefore, following the IUPAC naming conventions:

• Start with the ligands in alphabetical order, mentioning their number by prefixes like di- (for two), tri- (for three), etc., or omitting the prefix for one.
• Add the central metal name.
• Mention the oxidation state of the metal in Roman numerals enclosed in parentheses.
• If the compound has a charge, specify it at the end after the metal name.

So, the final name becomes: Diammine dichlorido platinum (II)

The other options are incorrect because:

(B) Diammine dichlorido platinum (IV): The oxidation state of Pt is determined to be \(+2\), not \(+4\).

(C) Diammine dichlorido platinum (0): The compound is neutral, so no oxidation state needs to be specified.

(D) Diimmine dichlorido platinum (IV): The prefix "diimmine" is not used for ammonia as it's a single \

\(NH_3\) molecule, not two connected \(NH_2\) units.
