Bakelite is the condensation polymer of formaldehyde and .................

Answer

To answer the question, "Bakelite is the condensation polymer of formaldehyde and .................", we need to identify the second monomer involved in the formation of Bakelite.

### Step-by-Step Solution:

1. **Identify the First Monomer**:
- The first monomer given in the question is formaldehyde. The chemical formula for formaldehyde is HCHO.

2. **Identify the Second Monomer**:
- The second monomer that reacts with formaldehyde to form Bakelite is phenol. The chemical formula for phenol is C6H5OH.

3. **Understand the Polymerization Process**:
- Bakelite is formed through a condensation reaction between formaldehyde and phenol. During this reaction, water (H2O) is eliminated as a byproduct.

4. **Write the Reaction**:
- The general reaction can be represented as:
\[ n \text{(C}_6\text{H}_5\text{OH)} + n \text{(HCHO)} \rightarrow \text{Bakelite} + n \text{(H}_2\text{O)} \]
- Here, 'n' represents the number of repeating units in the polymer chain.

5. **Conclusion**:
- Therefore, Bakelite is the condensation polymer of formaldehyde and phenol.

### Final Answer:
Bakelite is the condensation polymer of formaldehyde and phenol.
