1.     Name the following molecules.

2.     Draw the following molecules.

a.     3,4-dimethyl-2-pentanol

b.     4-chloro-2-methylbutanal

c.     p-nitrophenol

d.     acetone

e.     2,4,4-trimethyl-3-nonanone

3.     Return to problems 2 and 3 and classify all the alcohols.

4.     The below names are incorrect.  State what is wrong and give the correct name.

a.     2-methyl-1-butanone

b.     3-ethyl-1-butanol

c.     2,2-dichloro-5-heptanol

5.     Below is the structure of cholesterol.  Would you expect it to be particularly soluble in water?

6. The IR for an unknown compound is given below.  When burned on a copper wire, no change was seen in the flame.  No reaction was seen with Br₂ (in 1,1,1-trichloroethane) even when a catalyst was added.  However, if the compound was heated with concentrated sulfuric acid and then the Br₂ was added, the color disappeared.   What is most likely to be the class of the organic molecule?

7.   Predict the products for the following reactions.
