Question
**Title: Understanding Bond Participation and Hybridization in Lewis Structures**

**Description:**

In this educational exercise, we analyze a Lewis structure to determine bond participation and hybridization of a specific highlighted atom.

**Lewis Structure:**

The given structure is as follows:

```
   H
   |
H—C—C≡C—H
   |
   H
```

The highlighted atom is the second carbon (C) from the left.

**Questions:**

1. **In how many sigma bonds does the highlighted atom participate?**
2. **In how many pi bonds does the highlighted atom participate?**
3. **What is the orbital hybridization of the highlighted atom?**

**Analysis:**

- **Sigma Bonds:** Sigma bonds (σ bonds) are the first bonds formed between two atoms. The highlighted carbon atom forms sigma bonds with its neighboring atoms. Determine the total number of these bonds.

- **Pi Bonds:** Pi bonds (π bonds) form in addition to sigma bonds, usually in double or triple bonds. Identify the number of additional pi bonds the highlighted atom is involved in.

- **Orbital Hybridization:** Hybridization describes the mixing of atomic orbitals to form new ones suitable for bonding. Examine the bonding environment of the highlighted atom to ascertain its hybridization state.

This exercise aims to deepen the understanding of molecular geometry, bond formation, and hybridization concepts in organic chemistry.
