PASS
Increasing molecular weight... - CORRECT ANSWER-increases boiling point and melting point,
and decreases dispersion forces
Increasing molecular size.... - CORRECT ANSWER-increases dispersion forces
What makes a molecule chiral? - CORRECT ANSWER-It has a plane (NOT LINE) of symmetry
Chirality Center - CORRECT ANSWER-Tetrahedral carbon atom bonded to four different groups
polymer - CORRECT ANSWER-long chain molecule formed by linking together a lot of smaller
molecules
monomer - CORRECT ANSWER-repeating piece inside a polymer
free radical - CORRECT ANSWER-extremely reactive species containing one or more unpaired
electrons
, Polymerization Reaction - CORRECT ANSWER-Initiator molecule is added to free radical, and
takes new role as free radical. Cycle continues until two radicals encounter each other
High density polyethylene is... - CORRECT ANSWER-linear and straight
Low density polyethylene is... - CORRECT ANSWER-branched chain structure
Degree of polymerization - CORRECT ANSWER-molar mass of polymer / molar mass of
monomer
isotactic polymer - CORRECT ANSWER-polymer in which substituent groups are all on the same
side of the polymer chain
syndiotactic polymer - CORRECT ANSWER-substituent groups are arranged on alternate sides of
the chain
atactic polymer - CORRECT ANSWER-random
condensation polymer - CORRECT ANSWER-polymer made of monomers containing 2+
functional groups through a reaction with water as a byproduct
MUST INCLUDE COPOLYMERS
copolymer - CORRECT ANSWER-made of more than one type of monomer
block copolymer - CORRECT ANSWER-contains long sections of blocks of 2+ different monomers
thermoplastic - CORRECT ANSWER-melts/deforms from heat
