Ziegler -Natta catalyst is an organometallic compound of which metal

Options

A. Iron
B. Titanium
C. Rhodium
D. Manganese

Answer

**Step-by-Step Solution:**

1. **Understanding Ziegler-Natta Catalyst**: The Ziegler-Natta catalyst is used in the polymerization of alkenes to produce polymers like polyethylene. It consists of two main components: a transition metal compound and a metal alkyl compound.

2. **Identifying the Components**: The transition metal component is typically a transition metal such as titanium or vanadium. The metal alkyl component is usually an aluminum alkyl compound.

3. **Common Example of Ziegler-Natta Catalyst**: A common formulation of the Ziegler-Natta catalyst is triethylaluminum (C2H5)3Al combined with titanium tetrachloride (TiCl4).

4. **Determining the Metal**: In this catalyst, the transition metal that is primarily used is titanium. Therefore, the Ziegler-Natta catalyst is an organometallic compound of titanium.

5. **Conclusion**: Based on the information, the answer to the question is that the Ziegler-Natta catalyst is an organometallic compound of titanium.

**Final Answer**: Titanium
