Composition of Ziegler-Natta catalyst is

Options

A. `(Et_(3))_(3) Al* TiCl_(2)`
B. `(Me)_(3) Al* TiCl_(2)`
C. `(Et)_(3) Al* TiCl_(4)`
D. `(Et)_(3) Al* PtCl_(4)`

Answer

To determine the composition of the Ziegler-Natta catalyst, we can follow these steps:

### Step 1: Identify the Components of the Ziegler-Natta Catalyst
The Ziegler-Natta catalyst is primarily composed of two main components: a transition metal compound and an organometallic compound.

### Step 2: Specify the Transition Metal Compound
In the case of the Ziegler-Natta catalyst, the transition metal compound is typically titanium tetrachloride, which is represented as TiCl4.

### Step 3: Specify the Organometallic Compound
The organometallic compound used in the Ziegler-Natta catalyst is usually triethylaluminium, which can be represented as Al(C2H5)3 or simply as AlEt3, where "Et" stands for the ethyl group.

### Step 4: Combine the Components
The overall composition of the Ziegler-Natta catalyst can be expressed as a combination of these two components:
- Triethylaluminium (Al(C2H5)3)
- Titanium tetrachloride (TiCl4)

### Step 5: Write the Complete Formula
Thus, the complete representation of the Ziegler-Natta catalyst can be written as:
\[ \text{Al(C}_2\text{H}_5\text{)}_3 \cdot \text{TiCl}_4 \]

### Conclusion
Therefore, the composition of the Ziegler-Natta catalyst is triethylaluminium and titanium tetrachloride.
