Terylene is a polymer obtianed from

Options

A. Ethylene glycol and glycerol
B. Ethylene glycol and glyceraldehydes
C. Ethylene glycol and terphthalic acid
D. None of the above

Answer

To determine the monomers from which Terylene (also known as Dacron) is obtained, we can follow these steps:

### Step 1: Identify the Name of the Polymer
Terylene is a synthetic polymer commonly known as Dacron.

### Step 2: Identify the Monomer Units
Terylene is formed from two specific monomer units:
- **Ethylene Glycol**
- **Terephthalic Acid**

### Step 3: Write the Structures of the Monomers
1. **Ethylene Glycol**: The chemical structure is represented as:
\[ HO-CH_2-CH_2-OH \]
This shows that ethylene glycol has two hydroxyl (-OH) groups.

2. **Terephthalic Acid**: The chemical structure can be represented as:
\[ HOOC-C_6H_4-COOH \]
This indicates that terephthalic acid has two carboxylic acid (-COOH) groups attached to a benzene ring.

### Step 4: Polymerization Reaction
When these two monomers undergo a condensation reaction, one molecule of water is eliminated, resulting in the formation of Terylene. The reaction can be summarized as:
\[ \text{Ethylene Glycol} + \text{Terephthalic Acid} \rightarrow \text{Terylene} + H_2O \]

### Step 5: Structure of Terylene
The resulting polymer structure can be represented as:
\[ \text{[-O-CH}_2\text{-CH}_2\text{-O-C(=O)-C}_6\text{H}_4\text{-C(=O)-]}_n \]
This shows the repeating units of Terylene, where 'n' indicates the number of repeating units in the polymer chain.

### Conclusion
Thus, Terylene is a polymer obtained from the monomers ethylene glycol and terephthalic acid.

### Final Answer
Terylene is obtained from **Ethylene Glycol and Terephthalic Acid**.
