25.3.1 Organic Polymers

Question 1

Which statement about polymers is not correct?

Answer 1

Homopolymers are generally larger than heteropolymers.

Question 2

The drawing shows the synthesis of polyethylene. Structure 1 shows the individual monomers (four total), while Structure 2 shows the polymer polyethylene.

Which statement about this synthesis reaction is not correct?

Answer 2

In polyethylene, a σ bond links each monomer. This σ bond is made by the breaking of a σ bond in the original, separate ethylene molecules.

Question 3

Which statement about polyvinylchloride or polyisoprene is not correct?

Answer 3

Two π bonds are broken in the isoprene monomer to make polyisoprene.

Question 4

Which statement about the synthesis of a polymer is not correct?

Answer 4

A polymer has an activator molecule on one end and a terminator molecule on the other end. The actual terminator atom is usually a carbon atom.

Question 5

Let’s look at the synthesis of nylon.

Which statement about this reaction is not correct?

Answer 5

This synthesis reaction is an addition reaction.

Question 6

Polymers are __________

Answer 6

large molecules of repeating units of smaller molecules.

Question 7

Which statement about polymers is not correct?

Answer 7

A polymer with only one type of monomer can be called a heteropolymer.

Question 8

Which statement about the synthesis of polymers is not correct?

Answer 8

There are two types of polymer synthesis methods that differ by the reactants used in the reaction.

Question 9

Which statement about the synthesis of polyethylene is not correct?

Answer 9

The polymer bonding between individual monomers involves a carbon atom and a hydrogen atom.

Question 10

Look again at the synthesis of polyethylene.

Which statement about this event is not correct?

Answer 10

In the diagram, the polymer polyethylene is labeled “Structure 1.”
