Question

Which two monomers make combine to form a polyester O a carboxylic acid and an arnineO a pair of carboxylic acidsO a dicarboxylic acid and an alkeneO a dicarboxylic acid and a dihydroxy alcoholD

Answer 1

`D`

Step-by-step explanation:

Here, we want to know the constituent monomers of a polyester

Polyester is a condensation polymer that results from the combination of two different polymers

It is a condensation polymer since molecules of water are expunged from the product

The two different monomers are dicarboxylic acid and a diol (a di hydroxyl alcohol)
