Question

The IUPAC name of the Wilkinson's catalyst $\left[RhCl\right(PP{h}_3{)}_3]$ is

• A. Chlorotris (triphenylphosphine) rhodium (I)
• B. Chlorotris (triphenylphosphine) rhodium (IV)
• C. Chlorotris (triphenylphosphine) rhodium $\left(0\right)$
• D. Chlorotris (triphenylphosphine) rhodium (VI)

Answer 1

The correct option is A Chlorotris (triphenylphosphine) rhodium (I)

The IUPAC name of the Wilkinson's catalyst $\left[RhCl\right(PP{h}_3{)}_3]$ is Chlorotris (triphenylphosphine) rhodium (I).
The ligands chlorine and $PP{h}_3$ are named as chloro and triphenylphosphine. The prefix tris indicates three triphenylphosphine ligands.The metal is named as rhodium (I). The oxidation state of rhodium is written in roman numerals inside parenthesis.
