Bakelite is a/an

Options

A. addition polymer
B. thermoplastic polymer
C. elastomer polymer
D. thermosetting polymer

Answer

**Step-by-Step Solution:**

1. **Identify Bakelite**: Bakelite is a type of polymer. To classify it correctly, we need to understand its structure and formation.

2. **Determine the Type of Polymer**: Bakelite is known for its cross-linked structure. This means that the polymer chains are interconnected by covalent bonds, forming a three-dimensional network.

3. **Identify the Polymerization Process**: Bakelite is formed through a condensation polymerization process. In this type of polymerization, small molecules (like water or carbon dioxide) are released as by-products during the formation of the polymer.

4. **Classify Based on Thermal Properties**: Bakelite is classified as a thermosetting polymer. This means that once it is set into a shape, it cannot be remolded or reshaped upon heating. This characteristic is due to the strong covalent bonds formed during the cross-linking process.

5. **Evaluate the Options**: Given the definitions:
- Option 1: Addition polymer - Incorrect
- Option 2: Thermoplastic polymer - Incorrect
- Option 3: Elastomer polymer - Incorrect
- Option 4: Thermosetting polymer - Correct

6. **Conclusion**: Based on the analysis, Bakelite is classified as a thermosetting polymer.

**Final Answer**: Bakelite is a thermosetting polymer.
