Question

What monomer would you use to form each of the following polymers?

Short answer

Repeating units in a polymer chain determines the type of monomer present in it. The monomers used for the given polymers are,

a.

(Chloroethene)

1) Methyl methacrylate

2) CF₂=CF₂ (tetrafluoroethylene)

Step-by-step solution

Polymer (a-Polychloroethane)

Monomer units constitutes to give long chain polymers.The given polymer contains CH₂=CH-Cl as repeating unit. Thus, chloromethane is the monomer of polychloroethane.

Polymer (b-PMMA))

The given polymer contains CH₂=CCH₃-CO-OCH₃ as repeating monomer units. Thus, methyl methacrylate is the monomer of PMMA polymer.Structure of the monomer is shown below.

Polymer (c-Teflon)

Presence of similar monomer unit, tetrafluoroethane (CF₂=CF₂) constitute the polymer Teflon. Thus,tetrafluoroethylene is the monomer of polymer Teflon.Given below is the structure of the repeating unit in Teflon.

Thus, the monomer used in each polymer chain explained with its diagram.
