CHEM 219 PRINCIPLES OF ORGANIC
CHEMISTRY MODULE 7 AND 8 EXAM 2026
◉ Macromolecule. Answer: very large molecule composed of
thousands of covalently bonded atoms (ex: polymer)
◉ 1. natural (in nature)
2. synthetic (in lab). Answer: two ways polymers are made
◉ rubber, carbs: starch & cellulose, proteins, nucleic acids DNA, RNA.
Answer: natural polymers
◉ nylon, teflon, styrofoam, polyethylene, Dacron,. Answer: synthetic
polymers
◉ 1. method of formation
2. final composition
3. stereochemical orientation. Answer: 3 main ways to differentiate
polymers
◉ 1. chain-growth
2. step-growth. Answer: Two classifications of Synthetic polymers
,◉ addition polymers. Answer: chain growth polymers are also know
as:
◉ made by addition of one monomer unit to another in a repetitive
pattern. Answer: How are chain growth polymers made?
◉ chain growth polymerization. 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. Answer: what 2 things
stops chain growth polymerization?
◉ Teflon. Answer: chain-growth
polymer: polytetrafluoroethylene
monomer: F2C=CF2
nonstick coating, goretex, electrical insulator, chem-resistant coating
◉ Saran. Answer: chain-growth
polymer: polyvinylidenedichloride
, monomer: H2C=CCl2
cling-wrap
◉ Polypropylene. Answer: chain-growth
polymer: polypropylene
monomer: H2C=CHCH3
carpet fibers, car parts, toys, packaging, houseware
◉ Orlon, Acrilan, Creslan. Answer: chain-growth
polymer: polyacrylonitrile
monomer: H2C=CH(CN)
textiles/fibers, carpets, upholstery
◉ Polyvinyl Acetate. Answer: chain-growth
polymer: polyvinyl acetate
monomer: H2C=CH(OCOCH3)
elmers glue, silly putty, latex paints
◉ Polyvinyl alcohol. Answer: chain-growth
polymer: polyvinyl alcohol
monomer: H2C=CH(OH)
