Which of the following polymer is not synthesized from acidic monomer ?

Options

A. Nylon - 6, 6
B. Dacron
C. Bakelite
D. Teflon

Answer

To solve the question of which polymer is not synthesized from an acidic monomer, we will analyze each of the given options step by step.

### Step 1: Analyze Nylon 6-6
- **Monomers**: Adipic acid and hexamethylenediamine.
- **Type of Monomer**: Adipic acid is a dicarboxylic acid, which is acidic.
- **Conclusion**: Nylon 6-6 is synthesized from an acidic monomer.

**Hint**: Check the monomer structure and identify if it contains carboxylic acid groups.

### Step 2: Analyze Dacron
- **Monomers**: Dimethyl terephthalate and ethylene glycol.
- **Type of Monomer**: Dimethyl terephthalate is derived from terephthalic acid, which is also acidic.
- **Conclusion**: Dacron is synthesized from an acidic monomer.

**Hint**: Look for the presence of carboxylic acid groups in the monomers.

### Step 3: Analyze Bakelite
- **Monomers**: Phenol and formaldehyde.
- **Type of Monomer**: Phenol is a weak acid but not a carboxylic acid. It does not contain a carboxylic acid group.
- **Conclusion**: Bakelite is not synthesized from a traditional acidic monomer.

**Hint**: Identify if the monomer is a carboxylic acid or just a weak acid.

### Step 4: Analyze Teflon
- **Monomer**: Tetrafluoroethylene.
- **Type of Monomer**: Tetrafluoroethylene is an unsaturated hydrocarbon and does not contain acidic functional groups.
- **Conclusion**: Teflon is not synthesized from an acidic monomer.

**Hint**: Check if the monomer is an unsaturated compound or contains acidic groups.

### Final Conclusion
After analyzing all the options:
- **Nylon 6-6**: Acidic monomer (Adipic acid).
- **Dacron**: Acidic monomer (Terephthalic acid).
- **Bakelite**: Not synthesized from a traditional acidic monomer (Phenol).
- **Teflon**: Not synthesized from an acidic monomer (Tetrafluoroethylene).

The correct answer to the question "Which of the following polymer is not synthesized from acidic monomer?" is **Teflon**.

### Summary of Steps:
1. Identify the monomers of each polymer.
2. Determine if the monomers are acidic (carboxylic acids).
3. Conclude based on the presence or absence of acidic groups.
