Module 8 Portage 219 Organic
Chemistry Exam Questions With
100%Verified AnswersA+GRADED
Polymer - correct answer...✔✔large molecule made by repetitive linking of smaller
units (monomers)

Macromolecule - correct answer...✔✔very large molecule composed of thousands of
covalently bonded atoms (ex: polymer)

1. natural (in nature)
2. synthetic (in lab) - correct answer...✔✔two ways polymers are made

rubber, carbs: starch & cellulose, proteins, nucleic acids DNA, RNA - correct answer...
✔✔natural polymers

nylon, teflon, styrofoam, polyethylene, Dacron, - correct answer...✔✔synthetic
polymers

1. method of formation
2. final composition
3. stereochemical orientation - correct answer...✔✔3 main ways to differentiate
polymers

1. chain-growth
2. step-growth - correct answer...✔✔Two classifications of Synthetic polymers

addition polymers - correct answer...✔✔chain growth polymers are also know as:

made by addition of one monomer unit to another in a repetitive pattern - correct
answer...✔✔How are chain growth polymers made?

chain growth polymerization - correct answer...✔✔A polymerization involving
sequential addition to monomers that are unsaturated (C=C) or have some other
reactive functional groups (particularly ethylene and derivatives)

1. intervention
2. consumption of all available monomers - correct answer...✔✔what 2 things stops
chain growth polymerization?

Teflon - correct answer...✔✔chain-growth
polymer: polytetrafluoroethylene
