GCSE Chemistry - Condensation Polymers (Polyesters) #60

The video tutorial explains the formation of polyesters, a type of condensation polymer, through the combination of dicarboxylic acid and diol monomers. It details the process of forming ester links and the release of water molecules, highlighting the importance of functional groups. The tutorial also discusses the biodegradability of polyesters compared to non-biodegradable addition polymers like plastics.

What are the two types of monomers commonly used to form polyesters?

• Carboxylic acid and amine

• Amino acid and alcohol

• Diol and ketone

• Dicarboxylic acid and diol

What is formed when a dicarboxylic acid and a diol combine?

• A polyester and oxygen

• A polyester and water

• An addition polymer

• A polyester and carbon dioxide

Why do we use the letter 'N' in the formation of polyesters?

• To denote the number of monomers

• To indicate the number of ester links

• To specify the number of functional groups

• To represent the number of water molecules

What is a key requirement for monomers to form condensation polymers?

• They must be identical

• They must have at least two functional groups

• They must release oxygen during the process

• They must have at least one functional group

How do polyesters differ from addition polymers like plastics?

• Polyesters are made from a single monomer

• Polyesters are generally biodegradable

• Polyesters are non-biodegradable

• Polyesters do not form water molecules
