Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R. Assertion A : Dacron is an example of polyester polymer. Reason R : Dacron is made up of ethylene glycol and terephthalic acid monomers. In the light of the above statements, choose the most appropriate answer from the options given below.
Both A and R are correct and R is the correct explanation of A.
Both A and R are correct but R is NOT the correct explanation of A.
A is correct but R is not correct.
A is not correct but R is correct.
Show Solution
The Correct Option isA
Solution and Explanation
The given question presents an assertion and a reason related to the chemical substance Dacron. Let's analyze each statement:
Assertion A: Dacron is an example of a polyester polymer.
Dacron is indeed a trade name for a type of polyester fiber, commonly used in fabrics and textiles. Polyesters are polymers that contain the ester functional group in their main chain.
Reason R: Dacron is made up of ethylene glycol and terephthalic acid monomers.
The production of Dacron involves the reaction of ethylene glycol with terephthalic acid. This polymerization process results in the formation of polyethylene terephthalate (PET), which is the chemical name for the polymer known commercially as Dacron.
Given these explanations, we can conclude:
Both the assertion and the reason are correct. Dacron is a polyester polymer, and it is indeed made from the monomers ethylene glycol and terephthalic acid, which fits the description in the reason.
The reason "Dacron is made up of ethylene glycol and terephthalic acid monomers" correctly explains why Dacron is classified as a polyester polymer.
Therefore, the most appropriate answer is:
Both A and R are correct and R is the correct explanation of A.
