The correct IUPAC name of the complex $[Pt(NH_3)_2Cl_2]$ is:
Show Hint
- diamminedichloridoplatinum (IV)
- diamminedichloridoplatinum (II)
- dichloridodiammineplatinum (IV)
- dichloridodiammineplatinum (II)
The Correct Option is B
Solution and Explanation
IUPAC nomenclature rules for naming neutral coordination complexes.
Step 2: Meaning
Ligands are named first in strictly alphabetical order, followed by the central metal, and then its oxidation state is placed in Roman numerals inside parentheses.
Step 3: Analysis
The complex has two ammonia ligands ("ammine", starts with 'a') and two chloride ligands ("chlorido", starts with 'c').
Alphabetically, 'ammine' precedes 'chlorido', giving "diamminedichlorido".
The central metal is Platinum. Let its oxidation state be $x$. Since the overall complex is neutral:
$x + 2(0) + 2(-1) = 0 \implies x = +2$.
Step 4: Conclusion
Combining these components yields the name diamminedichloridoplatinum(II).
Final Answer: (B)
