Test Hints

Want to know what to study; well here it is. Ideas directly off the test.
These are random thoughts that come to mind as I make up these tests, may or may not be a 100% but it should be darn close. Not the order in which the materisl was covered.
Book references are not necessarily yours. I will colour code page references for you. See RED Pages .

Unit I Atomic Theory / Aggagates

know your electromagnetic spectrum
energy equations, photon, quanta
energy states, orbitals, s, p, d, f, order of
remember the selection rule n>l>=/m/
n, l, m, s what they mean and allowed numerical values
electron configuration and energy level diagram, know the difference and similarities between the two.
covalent bonding, ionic bonding coordinate covalent bonding, polar and nonpolar, Electronegativity difference of 1.7 is the pivot point
lattice sites ==> central atom, coordination number, orbital hybridization
types of attractive forces & where found, stong (ionic, covalent, metallic) and weak (van der Waals)
network solids 1-2-3 dimensional with examples and properties
properties of ionic, molecular, network, and metallic solids
bond angles, VSPER theory
molecular classification
NOTE: when the sum of bonding and nonbonding pairs does not equal the coordination number double bonds are a strong possibility.

Make sure you look at all the Internet notes and sites that were recomended to you.

Test 1 Oct 11 2001

This test will have a multiple choice section of about 30 or so. Then there is a section of Fill in the Blanks, but there will be lines left for longer answers. Fill in a chart, energy level diagram. Also, the multiple choice questions are done of a SCANTRON card; you bubble in the answers with a pencil, bring an eraser.

Unit II Organic

the various types of isomers ==> structural and geometric, cis & trans
functional groups and how to use them in nomenclature ==> writing formula from a structural picture and sketching a molecular diagram given the name.
recognizing and completing reactions given the reactants with necessary catalysts.
types of reactions: addition, elimination, substitution, combustion, halogenation, etc.
Polymers
- Condensation
- Addition
- Know examples of each
Tests for unsaturated compounds Bayer's solution
20 multiple choice, (Make sure you have a pencil) 12 or so nomeclature questions
reactions to complete using words and pictures
written response questions
make sure you know the following terms and concepts
- all the function groups and how to name
- crosslinkages and the type of polymers you get , thermal setting etc.
- reaction of permanganate ion with and alkene
- esterification and saponification
- geometric isomers -->cis - trans
- tests and reactions; what does what 1^o , 2 ^o & 3 ^o alcohols
- types of bonds ( Sigma Pi ) and hybridization orbitals that form these bonds. Book has pictures of this
- fatty acids example
