Question: Which of the following functional groups is commonly found in polyesters?

Options:

Correct Answer: Ester

Solution:

Polyesters are formed from the reaction of diols and dicarboxylic acids, which contain ester functional groups.

Which of the following functional groups is commonly found in polyesters?

Which of the following functional groups is commonly found in polyesters?

Step 1: Understand what polyesters are. They are a type of polymer made from repeating units.
Step 2: Know that polyesters are created by a chemical reaction between two types of molecules: diols and dicarboxylic acids.
Step 3: Identify the functional groups involved. Diols contain hydroxyl (-OH) groups, and dicarboxylic acids contain carboxyl (-COOH) groups.
Step 4: Recognize that when these two react, they form ester functional groups (-COO-), which are key components of polyesters.
Step 5: Conclude that the functional group commonly found in polyesters is the ester group.
