1. Chem. 1B – 12/10 Lecture

2. Announcements I Today –Complete Chapter 20 Material –Overview of Material since Exam 3 –Teaching Evaluations Grading –Make up quizzes graded (solutions posted); will replace lowest quiz score (most students); not updated onto Blackboard –I expect to update Blackboard by Tuesday Final Exam –Thursday, Dec. 17, 12:45-2:45 (sect. 2 to 6 here)

3. Announcements II Final Exam – cont. –Help Session (Tues. 12/15, 3:30-4:30, Sequoia 452) –Format(52 multiple choice questions – including two bonus questions – Bring Scantron SC982-E) –All material covered is possible for questions –Chapters where we spent more weeks (16 and 18) will have more questions –I will post some example organic chemistry problems –I tend to select what I think are easy questions that students haven’t done well at for repeat questions (Make up quiz example)

4. Announcements III Mastering Chemistry –Chapter 20 questions – due 12/15 Today’s Lecture –Organic Chemistry Aromatics (finish questions) Functional Groups –Review for Final Exam – since Exam 3 Chapter 24 Material Chapter 20 Material

5. Chapter 20 Organic Chemistry Mistake from Last Time 2.Give the names of the following compounds: NH 2 Br 2-butylbenzene (not isobutyl) or 2-phenylbutane

6. Chapter 20 Organic Chemistry Functional Groups What you need to know: Class name Identification Polar groups Alcohols ROH (R = rest of molecule) OH group is polar Example: CH 3 OH (methanol) Ethers ROR Example (CH 3 CH 2 OCH 2 CH 3 = diethyl ether)

7. Chapter 20 Organic Chemistry Functional Groups – cont. Ketones (R-C-R) O example: acetone somewhat polar Carboxylic Acids (R-C-OH) O Polar and acidic Amines (R 3 N) – note here one or two Rs can be Hs Polar and basic

8. Chapter 20 Organic Chemistry A Few Questions 1. Given the compound below, what functional groups does it have? a)alcoholb) aminec) alcohol and amine d) ketone and aminee) ketone and alcohol 2. Is that compound polar or non-polar? 3. CH 3 CH 2 CH 2 OCH 3 is a/an ________ a) alcoholb) ether c) ketone d) carboxylic acid

9. Final Exam Review Chapter 24 – Bonding Theory Common mistake on Exam 3 and Make Up Quiz – coordination complex electrons come from ligand lone pairs (not from metals or from other electrons on ligands) Know which d orbitals overlap more with ligand bonds in octahedral complexes and which overlap less Know how overlap leads to a split in the d orbital energies Know difference between low spin and high spin filling of d orbitals

10. Final Exam Review Chapter 24 – Bonding Theory Know how ligand (e.g. strong vs. weak) affects filling and  of coordination complexes Know how metal charge affects  of coordination complexes Be able to predict the d orbital electron configuration of coordination complexes (if known whether ligand is strong or weak) Know what causes coordination complexes to absorb light in visible, plus be able to calculate from  or visa versa

11. Final Exam Review Chapter 24 – Bonding Theory Be able to determine number of unpaired electrons and how that affects magnetic properties of complexes Understand why differences in energy levels occur for other geometries (tetrahedral, square planar) Chapter 20 – Carbon Bonding Know number of bonds formed by carbon in organic compounds Know hybridization and geometries (sp 3, sp 2, and sp for alkanes, alkene Cs, and alkyne Cs)

12. Final Exam Review Chapter 20 – Alkanes Know full structure and carbon skeleton representations Know names of alkanes (linear chain up to 10 carbons) Understand how a branched alkane is an isomer (plus how to name mono- and di-substituted alkanes) Be able to identify optical isomers and chiral carbons (not just for alkanes)

13. Final Exam Review Chapter 20 – Alkenes Be able to identify alkenes + know carbon skeleton representation Be able to give names of linear and branched alkenes Be able to identify cis- and trans- isomers and alkenes without cis-/trans- isomers Know names of alkanes (linear chain up to 10 carbons) Know effect of double bonds on melting points

14. Final Exam Review Chapter 20 – Alkynes Be able to identify, name and recognize carbon skeleton structure Chapter 20 – Reactions Be able to predict products and balance stoichiometry for combustion reactions Know halogenation reactions of alkanes Be able to predict products of hydrogenation and halogenation reactions involving alkenes (both + X 2 and + HX types)

15. Final Exam Review Chapter 20 – Reactions Know differences between alkene reactions and other reactions Chapter 20 – Aromatics Be able to identify, name and recognize carbon skeleton structure (up to two substituents plus common substituents mentioned) Chapter 20 – Functional Groups Be able to identify alcohol, ether, ketone, carboxylic acid, and amine functional groups Know which are functional groups are polar
