Wilkinson's catalyst, unsed as a catalyst in the hydrogenation of alkene is__________and is an example of ______catalysis .

Answer

**Step-by-Step Solution:**

1. **Identify Wilkinson's Catalyst**:
- Wilkinson's catalyst is known to be a rhodium complex, specifically rhodium(III) chloride. Its chemical formula is often represented as [RhCl(PPh₃)₃], where PPh₃ represents triphenylphosphine.

2. **Understand the Role of the Catalyst**:
- This catalyst is primarily used in the hydrogenation of alkenes. Hydrogenation is a chemical reaction that involves the addition of hydrogen (H₂) to unsaturated hydrocarbons (alkenes or alkynes) to convert them into saturated hydrocarbons (alkanes).

3. **Define the Type of Catalysis**:
- The process involving Wilkinson's catalyst is classified as homogeneous catalysis. In homogeneous catalysis, the catalyst and the reactants are in the same phase (usually liquid).

4. **Summarize the Findings**:
- Therefore, we conclude that Wilkinson's catalyst is Rhodium(III) chloride and is an example of homogeneous catalysis.

**Final Answer**:
Wilkinson's catalyst, used as a catalyst in the hydrogenation of alkene, is Rhodium(III) chloride and is an example of homogeneous catalysis.
