Example of condensation polymer is

Options

A. Formaldehyde ` to ` -meta-formaldehyde
B. Acetaldehyde `to ` para-aldehyde
C. Aceton `to` mesityl oxide
D. Ethene `to `polyethene

Explanation

To answer the question "Example of condensation polymer is," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Condensation Polymerization**:
- Condensation polymerization is a process where two or more monomers react to form a polymer and release a small molecule, often water (H2O), as a by-product.

2. **Identifying Examples of Condensation Polymers**:
- Common examples of condensation polymers include:
- Polyesters (formed from diols and dicarboxylic acids)
- Polyamides (formed from diamines and dicarboxylic acids)
- However, the question specifically asks for an example, so we will focus on specific compounds.

3. **Analyzing the Given Options**:
- The video mentions several compounds but focuses on acetone leading to mesityl oxide as a condensation polymer.
- Let's break down this reaction:
- Acetone (CH3COCH3) can undergo a condensation reaction to form mesityl oxide (C6H10O) with the elimination of water (H2O).

4. **Conclusion**:
- Based on the analysis, the example of a condensation polymer is **mesityl oxide**, which is formed from acetone.

### Final Answer:
The example of a condensation polymer is **mesityl oxide** (formed from acetone).
