Question

Given below are two statements : one is labelled as $\text{Assertion A}$ and the other is labelled as $\text{Reason R}$.
$\text{Assertion A}$ : Dacron is an example of polyester polymer.
$\text{Reason R}$ : 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.

• A. Both A and R are correct but R is NOT the correct explanation of A.
• B. A is correct but R is not correct
• C. Both A and R are correct and R is the correct explanation of A.
• D. A is not correct but R is correct.

Answer 1

The correct option is C Both A and R are correct and R is the correct explanation of A.

Dacron or Terylene is a condensation polymer formed by condensation reaction of ethylene glycol & terephthalic acid, with the removal water molecules. It is a polyester as in the polymeric chain an ester linkage is present joining the monomers.
