Thurs-Day 5
AP: FINAL TEST is tomorrow from 7:30 AM to 9:45AM... the exam will be similar to the AP exam except that part I will be half as long (45 minutes for about 37 questions). Do not miss this test for any reason. Based on your final test, I will let you know how you probably did on the AP exam.
See you tomorrow morning.
Honors AND Regents: we covered the all-important esterification reaction along with showing how to name esters and how to identify the alcohol and acid that reacted to form the ester. Esters are known for their pleasant fragrances.
We also covered combustion, fermentation, and polymerization.
Note on polymers:
the Regents is obsessed with your knowing several natural and synthetic (made in the laboratory) polymers.
Here is a list:
NATURAL (made by organisms): cellulose (cotton/wood), starch, rubber, DNA, RNA, proteins (polymers of amino acids), glycogen.
ARTIFICIAL: nylon, polyester, polyurethane, polyethene i.e. most plastics, latex.
We then did some more Regents review. The Jan. 2005 exam, fully explained is due tomorrow, Friday.
Also, you must preview the January 2006 exam (in your Orange Review Book) for tomorrow's class. I put a copy of that exam on EDLINE for now (later, the exam will be posted on the class website).
