According to the “Acorn” book, which is the AP
teacher’s guide, the following area should be covered: “Introduction to
organic chemistry: hydrocarbons and functional groups (structure, nomenclature,
chemical properties).” Typically,
this is an area that is not given great import or weight on the AP exam.
Usually a few multiple choice questions arise that are organic related.
However, in the past years organic chemistry has shown up in the free
response section. Because of this I
thought you could take some time over this two-week break to briefly review the
basics of organic chemistry. I know
that you have all had some organic chemistry in whatever first year course you
took, whether in the summer or Chemistry or Chemistry Honors.
In
particular, I am asking that you do the following:
1.
read through chapter 22 focusing on sections 1-3 and 5.
2.
pay particular attention to basic nomenclature of hydrocarbons up to ten
carbons (decane) in sections 22.1, 22.2 and 22.3
3.
look carefully at the functional groups and the naming clues for these as
summarized on page 1077 in section 22.5
4.
work through the questions at the bottom of the page
We will have a quiz on Tuesday, January 6, 2004, when we
return on this topic. Working
through the questions recommended will prepare you well for the quiz.
Use the opportunity as you read through this chapter to refresh your
memory on IMFs, basic structural characteristics of molecules including shape,
bond angles, hybridization and orbital overlap bonding concepts.
Draw two different molecules, structural isomers, that have the chemical formula, C2H6O. The two structures should have two different functional groups. Compare these two molecules in terms of properties like volatility, boiling points, DHvap and solubility in water. Would they differ in terms of DHcombustion?
