The phases present as the pressure on a sample of CO 2 is steadily increased from 0 .1 atm at a constant temperature of 200 K have to be described. Concept introduction: The physical state of a substance under different conditions of temperature and pressure is represented by a phase diagram which is drawn by taking pressure on the y axis and temperature on the x axis. One component system is a system involving one pure substance in different phases. The system is defined by a set of variables and the minimum number of variable used to define the system is called its degree of freedom.

These are synthesis questions. You need to show how the starting material can be converted into the product(s) shown. You may use any reactions we have learned. Show all the reagents you need. Show each molecule synthesized along the way and be sure to pay attention to the regiochemistry and stereochemistry preferences for each reaction. If a racemic molecule is made along the way, you need to draw both enantiomers and label the mixture as "racemic". All of the carbon atoms of the products must come from the starting material! ? H H

Q5: Draw every stereoisomer for 1-bromo-2-chloro-1,2-difluorocyclopentane. Clearly show stereochemistry by drawing the wedge-and-dashed bonds. Describe the relationship between each pair of the stereoisomers you have drawn.
