Chemistry - Polymer Question with Solution | TestHub
Of the following which one is classified as polyester polymer?
Options:
Answer:
Solution:
Question Explanation:
The question asks to identify the polymer from the given options that belong to the polyester class, which is defined by having ester linkages.
Concept :
This question is based on classification of polymers on the basis of polymer linkages.
Solution −
A polyester is a polymer that contains repeating ester linkages (−COO- ) in its main chain. These are typically formed through the condensation reaction of a diol and a dicarboxylic acid. Terylene, also known as polyethylene terephthalate (PET), is a prime example of a polyester, as it is synthesized from ethylene glycol (a diol) and terephthalic acid (a dicarboxylic acid). The other options are different types of polymers: Bakelite and Melamine formaldehyde are thermosetting resins with complex linkages, while Nylon-6,6 is a polyamide with amide linkages (−CONH- ). Final Answer : Correct Option is (A)
