Concept introduction:
Any polymer can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry). Naming of polymer is based on the monomer from which it was derived.
If the monomer contains only one word in the name then no parenthesis is used when naming polymer but if the monomer contains two words means parenthesis is used around the name of monomer.
Monomer with two words=poly(monomer)
Monomer with single word=poly-monomer

Answer to Problem 22PP
The polymer is polynitroethylene and the structure is
Explanation of Solution
To draw and name the polymer when vinyl acetate undergoes polymerization
Draw the structure of nitroethylene
The structure of nitroethylene is drawn following
Polymerization of nitroethylene
The nitroethylene has a double bond which can involve in polymerization with another nitroethylene which propogates to the other molecules to form a chain where the repeating unit is the monomer unit without a double bond as it is involved in polymerization. nitroethylene polymerizes to form polynitroethylene
(b)
Interpretation:
Chemical structure of the polymer should be drawn and named when given monomer undergoes polymerization.

The polymer is poly(vinylidene fluoride) and the structure is
Explanation of Solution
To draw and name the polymer when vinylidene fluoride undergoes polymerization
Draw the structure of vinylidene fluoride
The structure of vinylidene fluoride is drawn following IUPAC nomenclature.
Polymerization of vinylidene fluoride
The vinylidene fluoride has a double bond which can involve in polymerization with another vinylidene fluoride which propogates to the other molecules to form a chain where the repeating unit is the monomer unit without a double bond as it is involved in polymerization. vinylidene fluoride polymerizes to form poly(vinylidene fluoride). As this monomer has two words in its name the polymer is named with paranthesis

- 32. Consider a two-state system in which the low energy level is 300 J mol 1 and the higher energy level is 800 J mol 1, and the temperature is 300 K. Find the population of each level. Hint: Pay attention to your units. A. What is the partition function for this system? B. What are the populations of each level? Now instead, consider a system with energy levels of 0 J mol C. Now what is the partition function? D. And what are the populations of the two levels? E. Finally, repeat the second calculation at 500 K. and 500 J mol 1 at 300 K. F. What do you notice about the populations as you increase the temperature? At what temperature would you expect the states to have equal populations?arrow_forward30. We will derive the forms of the molecular partition functions for atoms and molecules shortly in class, but the partition function that describes the translational and rotational motion of a homonuclear diatomic molecule is given by Itrans (V,T) = = 2πmkBT h² V grot (T) 4π²IKBT h² Where h is Planck's constant and I is molecular moment of inertia. The overall partition function is qmolec Qtrans qrot. Find the energy, enthalpy, entropy, and Helmholtz free energy for the translational and rotational modes of 1 mole of oxygen molecules and 1 mole of iodine molecules at 50 K and at 300 K and with a volume of 1 m³.
