Understanding Dacron Polyester Formation
Dacron is a type of polyester, a synthetic polymer formed through a specific chemical reaction between certain organic compounds. The correct answer to the question is option 'A': Terephthalic acid and ethylene glycol.
Components of Dacron
- Terephthalic Acid:
- A dicarboxylic acid with the formula C8H6O4.
- It contains two carboxylic acid (-COOH) groups, which are crucial for forming the polymer chains.
- Ethylene Glycol:
- A simple diol with the formula C2H6O2.
- It contains two hydroxyl (-OH) groups, allowing it to react with the carboxylic acid groups.
Polymerization Process
- Esterification Reaction:
- When terephthalic acid and ethylene glycol are combined, they undergo a condensation polymerization reaction.
- Each carboxylic acid group from terephthalic acid reacts with a hydroxyl group from ethylene glycol, releasing water in the process.
- Formation of Dacron:
- This reaction continues, resulting in long chains of the polyester Dacron, characterized by the repeating units linked by ester bonds (-COO-).
Why Other Options Are Incorrect
- Option B: Benzoic acid and para HO – (C6H4) – OH
- This combination does not yield a polyester with the same properties as Dacron.
- Option C: Propylene and para HO – (C6H4) – OH
- This reaction would not produce a polyester but rather different types of polymers.
- Option D: Benzoic acid and ethanol
- While this can form an ester, it does not produce the specific polyester Dacron.
In summary, Dacron is formed specifically from the reaction of terephthalic acid and ethylene glycol, making option 'A' the correct answer.
