C11 - Polymers

Question 1

Polymers

Answer 1

A substance made from very large molecules made up of many repeating units

Question 2

Monomers

Answer 2

Small reactive molecules that react together in repeating sequences to form a very large molecule (a polymer)

Question 3

Addition polymerisation

Answer 3

The reaction in which in which unsaturated monomers (containing C=C bonds) join together to make a polymer as the only product.

Question 4

Condensation polymerisation

Answer 4

The reaction in which two monomers with two different functional groups join together to form a polymer plus a small molecule (such as H2O or HCl) as the other product

Question 5

Proteins

Answer 5

Polymers made from different amino acid monomers

Question 6

DNA (Deoxyribonucleic acid)

Answer 6

A large organic molecule that encodes genetic instructions for the development and functioning of living organisms and viruses

Question 7

Nucleotides

Answer 7

The monomers which make up DNA. The nucleotides are based on the sugar deoxyribose, bonded to a phosphate group and a base. There are four possible bases that bond to the sugar

Question 8

Polysaccharides

Answer 8

Polymers in which simple carbohydrates (monosaccharides) polymerise to make polymers such as starch and cellulose
