Question

Dacron is a polymer of ?

• A. Glycol and Phenol
• B. Glycol and Terephthalic acid
• C. Glycol and Formaldehyde
• D. Glycol and Phthalic acid

Answer 1

The correct option is B

Glycol and Terephthalic acid

Explanation for the correct option:

Option(B): Glycol and Terephthalic acid

• Polymers are known as materials made of long, repeating monomer chains of molecules, which have different properties, depending on the type of molecules with which they are bonded with.
• Ethylene glycol and Terephthalic acid undergo condensation polymerization to form Dacron, which has the properties like high tensile strength, high resistance to degradation by chemical bleaches, and abrasion.
• The condensation polymerization reaction between Ethylene glycol and Terephthalic to produce the polymer Dacron can be shown as:

Explanation for the correct option:

Option(A): Glycol and Phenol

• Dacron is not a polymer of Glycol and Phenol.
• Hence, the given option does not correspond to the correct concept.

Option(C): Glycol and Formaldehyde

• Glycol and Formaldehyde don't form the polymer Dacron.
• Hence, the given option does not represent the correct concept.

Option(D): Glycol and Phthalic acid

• Dacron is not a polymer of Glycol and Phthalic acid.
• Thus the given option is an incorrect one.

Hence, Dacron is a polymer of Glycol and Terephthalic acid.
