The suitable catalyst in hydrogenation of oil is:

Options

A. Fe
B. Pt
C. Ni
D. Mo

Explanation

To determine the suitable catalyst in the hydrogenation of oil, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Hydrogenation**:
- Hydrogenation is a chemical process that involves the addition of hydrogen (H₂) to unsaturated fats or oils. This process converts liquid oils into solid or semi-solid fats.

2. **Identifying the Purpose of Hydrogenation**:
- The primary purpose of hydrogenation is to increase the stability and shelf life of oils, as well as to improve their texture and flavor.

3. **Catalysts in Hydrogenation**:
- A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. In the case of hydrogenation, certain metals are used as catalysts.

4. **Common Catalysts Used**:
- The most commonly used catalysts for the hydrogenation of oils include:
- Nickel (Ni)
- Platinum (Pt)
- Palladium (Pd)

5. **Selecting the Most Suitable Catalyst**:
- Among these, nickel is the most widely used catalyst for the hydrogenation of vegetable oils due to its effectiveness, availability, and cost-effectiveness. Platinum and palladium are also effective but are more expensive and less commonly used for large-scale hydrogenation processes.

6. **Conclusion**:
- Therefore, the suitable catalyst in the hydrogenation of oil is **Nickel (Ni)**.
