(a)

Interpretation Introduction

Interpretation:

The Lewis structure for monomer acrylonitrile has to be drawn.

Concept Introduction:

Lewis structure for any molecule is drawn by using the following steps,

First the skeletal structure for the given molecule is drawn then the total number of valence electrons for all atoms present in the molecule is determined

The next step is to subtract the electrons in total number of bonds present in the skeletal structure of the molecule with the total valence electrons such that considering each bond contains two electrons with it.

Finally, the electrons obtained after subtractions have to be equally distributed such that each atom contains eight electrons in its valence shell.

(b)

Interpretation Introduction

Interpretation:

The poisonous gas released in case of fire of rugs and upholstery has to be identified.

Concept Introduction:

Combustion reaction: It is the reaction in which hydrocarbons are heated in presence of oxygen results to give water and carbon dioxide with heat.

Polymers: Polymers are macromolecules which are formed a by number of repeating units called monomers.

2) (4 pt) After the reaction was completed, the student collected the following data. Crude product data is the data collected after the reaction is finished, but before the product is purified. "Pure" product data is the data collected after attempted purification using recrystallization. Student B's data: Crude product data "Pure" product data after recrystallization Crude mass: 0.93 g grey solid Crude mp: 96-106 °C Crude % yield: Pure mass: 0.39 g white solid Pure mp: 111-113 °C Pure % yield: a) Calculate the crude and pure percent yields for the student's reaction. b) Summarize what is indicated by the crude and pure melting points.
