What type of multiple bonds are involved in the compounds containing C `-=`C, C`-=` O and -C`-=` N groups ?

Explanation

To solve the question regarding the types of multiple bonds involved in the compounds containing C≡C, C≡O, and C≡N groups, we need to analyze each of these bonds step by step.

### Step-by-Step Solution:

1. **Understanding Multiple Bonds**:
- Multiple bonds consist of sigma (σ) and pi (π) bonds. A sigma bond is formed by the head-on overlap of atomic orbitals, while pi bonds are formed by the side-to-side overlap of p-orbitals.

2. **Analyzing C≡C (Carbon-Carbon Triple Bond)**:
