5B.1 Polymerisation reactions

Question 1

what are polymerization reactions considered

Answer 1

addition reaction since the vast alkene would add up to form a polymer

Question 2

what is a monomer

Answer 2

small molecules that add up to form a polymer

Question 3

what is the polymer of ethene

Answer 3

poly(ethene) or polythene

Question 4

what is the polymer of propene

Answer 4

poly(propene) or polypropylene

Question 5

what is the polymer of chloroethene

Answer 5

poly(chloroethene) or polyvinyl cholride PVC

Question 6

what is the polymer of tetrafluoroethene

Answer 6

poly(tetrafluoroethene) or PTFE teflon

Question 7

what is the polymer of phenylethene

Answer 7

poly(phenylethene) or polyseter

Question 8

what is a repeat unit

Answer 8

a set of atoms that are joined together in large numbers to produce the polymer structure

Question 9

why do we use the letter n in polymerization

Answer 9

because the polymers dont have a fixed molecular formula since it’s molecular mass may be anything from thousands to millions
