Packet 3: Bonus 17

Simulation of these molecules can be simplified with the rotational isomeric state model. For 10 points each:
[10e] Name these molecules that can be synthesized via step-growth or chain-growth methods.
ANSWER: polymers
[10m] Monomers in the rotational isomeric state model assume discrete states denoted trans, [this adjective]-plus, or [this adjective]-minus. An effect named for this adjective applies to scenarios in which a namesake conformation is more stable than the anti conformation.
ANSWER: gauche [accept gauche-plus or gauche-minus; accept gauche effect]
[10h] A polymer’s physical properties must be described with random walks when chain size is greater than this quantity. This quantity is defined as the polymer’s bending stiffness divided by Boltzmann’s constant times temperature, and is usually half the Kuhn length.
ANSWER: persistence length [prompt on length]
