AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the identification of Wilkinson's catalyst from the given options. 2. **Analyzing the Options**: - **Option A**: Nickel - This is a common catalyst but not Wilkinson's catalyst. - **Option B**: C6H5 (triphenyl)3P-RhCl - This is a complex that includes rhodium and triphenylphosphine. - **Option C**: Lithium aluminium hydride - This is a reducing agent, not a catalyst. - **Option D**: Fe2O3 - This is iron(III) oxide, not related to Wilkinson's catalyst. 3. **Identifying Wilkinson's Catalyst**: - Wilkinson's catalyst is specifically known as chlorotris(triphenylphosphine)rhodium(I), represented as RhCl(PPh3)3. - It is used primarily for the hydrogenation of alkenes. 4. **Conclusion**: Based on the analysis, the correct answer is **Option B**: RhCl(PPh3)3, which is chlorotris(triphenylphosphine)rhodium(I). ---
