Identify the correct statements:

Options

A. Fluroine is a super halogen
B. iodine shows lewis basic nature
C. AgF is insoluble in water
D. `SCN^(-)` is a pseudohalide

Explanation

To solve the question of identifying the correct statements, we will analyze each statement one by one based on our knowledge of chemistry, particularly the properties of halogens and related compounds.

### Step-by-Step Solution:

1. **Statement 1: Fluorine is a super halogen.**
- **Analysis:** Fluorine is indeed the most reactive halogen and is known for its ability to form strong bonds with other elements. Its high electronegativity and reactivity qualify it as a "super halogen."
- **Conclusion:** This statement is **True**.

2. **Statement 2: Iodine shows Lewis basic nature.**
- **Analysis:** Lewis bases are defined as species that can donate a pair of electrons. Iodine has lone pairs of electrons that can be donated, thus it can act as a Lewis base.
- **Conclusion:** This statement is **True**.

3. **Statement 3: AgF is insoluble in water.**
- **Analysis:** Silver fluoride (AgF) is known to be highly soluble in water. The presence of fluorine, which is highly electronegative, contributes to the polarity of AgF, allowing it to dissolve in the polar solvent water.
- **Conclusion:** This statement is **False**.

4. **Statement 4: SCN⁻ is a pseudo halide.**
- **Analysis:** Pseudo halides are polyatomic ions that resemble halogens in their behavior. The thiocyanate ion (SCN⁻) behaves similarly to halides and is classified as a pseudo halide.
- **Conclusion:** This statement is **True**.

### Final Conclusion:
The correct statements are **1, 2, and 4**.
