CHEM134 C001 SPRING DIGITAL ACID
BASE CHEMISTRY BEYOND LABZ FINAL
PAPER QUESTIONS AND SOLUTIONS
◉ Chirality Center
Answer: Tetrahedral carbon atom bonded to four different groups
◉ polymer
Answer: long chain molecule formed by linking together a lot of
smaller molecules
◉ monomer
Answer: repeating piece inside a polymer
◉ free radical
Answer: extremely reactive species containing one or more
unpaired electrons
◉ Polymerization Reaction
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...
, Answer: linear and straight
◉ Low density polyethylene is...
Answer: branched chain structure
◉ Degree of polymerization
Answer: molar mass of polymer / molar mass of monomer
◉ isotactic polymer
Answer: polymer in which substituent groups are all on the same
side of the polymer chain
◉ syndiotactic polymer
Answer: substituent groups are arranged on alternate sides of the
chain
◉ atactic polymer
Answer: random
◉ condensation polymer
Answer: polymer made of monomers containing 2+ functional
groups through a reaction with water as a byproduct
MUST INCLUDE COPOLYMERS
