Question 1

What is a condensation reaction?

Answer 1

Reaction in which 2 molecules react together to form one larger molecule and one smaller molecule

Question 2

What is an ester?

Answer 2

Product of when carboxylic acid reacts with an alcohol

Question 3

What are condensation polymers?

Answer 3

Substance with molecules made from many repeat units, formed by condensation reactions

Question 4

Are proteins condensation polymers?

Answer 4

Yes, they are condensation polymers formed from amino acids

Question 5

What are the 2 main types of artificial condensation polymers?

Answer 5

Polyesters and polyamides

Question 6

What are polyesters made from?

Answer 6

A carboxylic acid with 2 carboxyl groups, and an alcohol with 2 hydroxyl groups

Question 7

Why are polyesters called polyesters?

Answer 7

Because they contain many ester groups

Question 8

What are polyamides made from?

Answer 8

A carboxylic acid with 2 carboxyl groups, and an ‘amine’ with 2 amino groups

Question 9

Why are polyamide called polyamides?

Answer 9

Because they contain many aside groups

Question 10

Does addition polymerisation need a catalyst at high temperatures and pressures?

Answer 10

Yes

Question 11

Does condensation polymerisation need a catalyst at high temperatures and pressures?

Answer 11

No, it can happen without a catalyst at room temperature and pressure
