EXAM II scheduled for Tuesday (November 6). Emphasis
is on Chapter 5 (stereochemistry) with some questions from Chapter 4 (refer
to last quiz on Chapter 4). Exam consists of 25 multiple choice questions to
be answered in 1 hr 15 minutes. Assignment for Thursday is to read Chapter
6. Homework assignment will be posted in Homework Section.
Week of 10/22. Check
out ALL the new web sites posted below and on other sections of web
Carefully review the concept of chirality, enantiomers
and diastereomers, especially the R-S System of Cahn-Ingold-Prelog for naming
enantiomers.
Understand what racemic mixtures are, optical rotation
of molecules and Fisher Projections. Review molecules with more than one
chirality center and the separation of enantiomers.
Week of 10/15: Finish assigned problems from Chapter 4. Study
conformation of Alkanes using Newman Projections and Sawhorse Formulas pp
148-153 and Conformations of Cyclohexane pp 156-166, Index of Hydrogen
Deficiency (pp 169-171). Synthesis of Alkanes and Cycloalkanes pp
168-169. Go over the CAS formula (N = S + A + 1) for predicting the number of
rings in an aliphatic cycloalkane (pg 166)
Start to read through Chapter 5 on Stereochemistry and Chiral Molecules
