Chemical structure of the
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.

Answer to Problem 22PP
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

- In intercalation compounds, their sheets can be neutral or have a negative or positive charge, depending on the nature of the incorporated species and its structure. Is this statement correct?arrow_forwardThis thermodynamic cycle describes the formation of an ionic compound MX2 from a metal element M and nonmetal element X in their standard states. What is the lattice enthalpy of MX2 ? What is the enthalpy formation of MX2 ? Suppose both the heat of sublimation of M and the ionization enthalpy of M were smaller. Would MX2 be more stable? Or less? or impossible to tell without more information?arrow_forward7. Draw the mechanism to describe the following transformation: Note: This is a base catalyzed reaction. So, the last steps must make [OH]- OH [OH]¯ OH Heat Oarrow_forward

QUESTION Liquid A is known to have a lower viscosity and lower surface tension than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment Liquid A and Liquid B are each pumped through tubes with an inside diameter of 27.0 mm, and the pressures PA and PB needed to produce a steady flow of 2.4 mL/s are measured. 25.0 mL of Liquid A are poured into a beaker, and 25.0 mL of Liquid B are poured into an identical beaker. Stirrers in each beaker are connected to motors, and the forces FA and FB needed to stir each liquid at a constant rate are measured. predicted outcome OPA will be greater than PB OPA will be less than PB OPA will be equal to PB It's impossible to predict whether PA or PB will be greater without more information.…arrow_forward
