We learned that chemical potential energy is stored in the bonds between atoms. Reactants and products have differing amounts of stored energy, so reactions either release or absorb energy.  We call these reactions endothermic or exothermic reactions, depending on the direction of energy flow.Consult the text on p.298-299 and 302-303 for help.
Homework:  Read p.298-299 and record bold terms and definitions; answer p.300 #1-5

Test today, pesticides assignment due tomorrow !  Good thing it's out of the way before the weekend.  Make sure yesterday's homework has also been completed.  Bring a calculator to class from now on.

When energy moves from one object to another, it is called heat.  The amount of energy transferred depends on mass of the object, how well it stores energy (specific heat capacity, found in tables on p.301 & 799), and the change in temperature of the object.  Refer to the text p.301-302 for help with solving the problems.  If you need help with significant digits, consult p.779.
Homework:  p.302 #8-12 for Friday

We reviewed stereoisomers, then used the rest of the period to study for the test on Thursday.  You have the Pesticide Use assignment due Friday.  The rubric for the Pesticide Use assignment is on the Unit 2 page of the SCH 4U site.

Synthetic fabrics are not made from addition polymers.  Polyester and nylon are both condensation polymers.  Read p.108-112 in the text for help.
Homework:  p.111 #1-3; p.113 (Section) #3-6

Read the text reference p.100-106 about addition polymers.  Know how to draw polymer structures from the monomer, monomers from the polymer, and repeating units as a condensed structure of the polymer.
Homework:  Answer p. 102 #1, 2; p.107 Practice #4, Section #1-5, 7
Review for the test next Tuesday is p.150-151 #1-14, 16, 17, 19-24; p.152-155 #1-3, 6, 7, 9, 10 (omit f; circle with line through it represents benzene), 16, 21, 23ab.  There are a few more review questions on a handout.
Complete the pesticide assignment, found on the Unit 2 web page of the grade 12 course, by next Friday, Oct. 29. 

Organic Chemistry Unit Test is on Thursday, Oct. 28, 2010
The three major types of organic reactions are substitution, addition, and elimination.  We defined them, and learned how to identify them.  You are to decide how to identify the other types of reactions we have learned about.
The different classes of organic chemicals were presented to you in pairs because each pair shared a functional group.  We discussed a few of the other similarities and differences in names and structures of the different classes of chemicals. 
There was a handout provided for practice in identifying types of organic reactions and in predicting products of reactions.  Complete this for homework.

We discussed how to name and draw amines and amides, and compared their properties to those of alkanes.  The method for naming amines is incorrect in the text.  The longest carbon chain bonded to the nitrogen is the main chain.  Replace the -e of the alkane name with the carbon number to which the nitrogen is bonded, then the suffix -amine.  Alkyl groups bonded to the nitrogen are given the location -N-.  E.g. N,4-dimethylhexan-2-amine
Homework:  p.72 #1-3; p.76 #4-6; p.77-78 #7, 10
Quiz tomorrow on functional group nomenclature.

The carboxyl group can form either a carboxylic acid or an ester.  We discussed how to name these hydrocarbon derivatives, and the reactions they undergo.  The text instructions are valid:  read p.58-67.
Homework:  p.60 #1, 2, IUPAC only; p.63 # 3-5; p.66 #11, 12; p.67 #13
Quiz Thursday on functional groups
Unit 2 test next Thursday, Oct.28, 2010

Due to the assembly, there was no class.  Your lab report was due today.  Please hand it in tomorrow if you haven't already done so.
