Terylene is the polymer of

Options

A. Ethylene glycol and terepthalic acid
B. Melamine and formaldehyde
C. Vinyl chloride and formaldehyde
D. hexamethylene diamine and adipic acid

Answer

To determine the polymer of Terylene, we need to analyze the options provided in the question.

### Step-by-Step Solution:

1. **Identify Terylene**: Terylene is a type of polyester, commonly known as Dacron. It is primarily used in textiles and other applications due to its durability and resistance to wrinkles.

2. **Examine the Options**: The question provides four options:
- (a) Ethylene glycol and terephthalic acid
- (b) Melamine and formaldehyde
- (c) Vinyl chloride and formaldehyde
- (d) Hexamethylenediamine and adipic acid

3. **Analyze Each Option**:
- **Option (a)**: Ethylene glycol and terephthalic acid are known to undergo a condensation reaction to form Terylene (Dacron). This is the correct option.
- **Option (b)**: Melamine and formaldehyde react to form melamine-formaldehyde resin, which is not Terylene.
- **Option (c)**: Vinyl chloride and formaldehyde do not form a polymer that is Terylene.
- **Option (d)**: Hexamethylenediamine and adipic acid react to form nylon, not Terylene.

4. **Conclusion**: Based on the analysis, the correct answer is option (a) Ethylene glycol and terephthalic acid, as these two components are used to synthesize Terylene.

### Final Answer:
Terylene is the polymer of **ethylene glycol and terephthalic acid**.
