We reviewed endothermic and exothermic reactions from Grade 11, focusing 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, lab report due tomorrow, pesticides assignment due Thursday!  Good thing it's out of the way before Easter weekend.  The Discussion questions and rubric for the lab report are on the Unit 2 page of this site.

Experiment is on p.138-140 of the text.  Complete a lab report that has title, purpose, observations, discussion FROM THE HANDOUT, conclusion.  The report is due on Wednesday, March 31, 2010.

We used the period to study for the test on Tuesday.  You will have an experiment to do on Monday, which will be due Wednesday.  You have the Pesticide Use assignment due Thursday.  The rubric for the Pesticide Use assignment is now on the Unit 2 page of the SCH 4U site.

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.
Complete the pesticide assignment, found on the Unit 2 web page of the grade 12 course, by next Thursday, April 1.  NO FOOLIN'!

Organic Chemistry Unit Test is on Tuesday, March 30, 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.  There are other similarities and differences in names and structures of the different classes of chemicals.  You are to find two more.
There was a handout provided to show how to write a lab report properly and how to use subscripts in word processors.
There was a handout provided for practice in naming and writing formulas of functional groups.
A third handout provides 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

We used molecular model kits to do the activity on p.90 of the text.  If you were absent, try choosing a reactant for each of the reactions listed in the table for the activity (except #9) and draw the organic structure for it and for the products of the indicated reaction.
If you were one of the many students who missed classes this week, please come for extra help on Monday and Wednesday when March break is over.  We only have about a week left in this unit.

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.  Read p.58-67.
Homework:  p.60 #1, 2, IUPAC only; p.63 # 3-5; p.66 #11, 12; p.67 #13.
