Options

A. `pi`-bond
B. `sigma`-bond
C. ionic bond
D. None

Explanation

To solve the question "Overlapping of 2 hybrid orbitals can lead to the formation of:", we need to understand the concept of hybrid orbitals and how they interact to form bonds.

### Step-by-Step Solution:

1. **Understanding Hybrid Orbitals**:
Hybrid orbitals are formed by the mixing of atomic orbitals (s, p, d) to create new orbitals that are degenerate (of the same energy). These hybrid orbitals are used in the formation of covalent bonds.

**Hint**: Remember that hybridization involves the combination of different types of atomic orbitals.

2. **Types of Bonds**:
In covalent bonding, there are two main types of bonds: sigma (σ) bonds and pi (π) bonds. Sigma bonds are formed by the head-on overlapping of orbitals, while pi bonds are formed by the side-to-side overlapping of orbitals.

**Hint**: Recall the difference between sigma and pi bonds in terms of their formation.

3. **Formation of Sigma Bonds**:
When two hybrid orbitals overlap, they can form a sigma bond. This is because the overlapping occurs along the internuclear axis, which allows for maximum overlap and thus a strong bond.

**Hint**: Sigma bonds are characterized by their axial symmetry along the bond axis.

4. **Examples of Sigma Bond Formation**:
- **SS Overlap**: Two s orbitals overlapping (e.g., H2 molecule).
- **SP Overlap**: One s orbital and one p orbital overlapping (e.g., HF molecule).
- **PP Overlap**: Two p orbitals overlapping (e.g., F2 molecule).

**Hint**: Think of specific molecular examples where these overlaps occur.

5. **Conclusion**:
Since the question specifically asks about the overlapping of two hybrid orbitals, we conclude that this overlapping leads to the formation of a sigma bond.

**Final Answer**: Overlapping of 2 hybrid orbitals can lead to the formation of a **sigma bond**.
