2 Welcome! Welcome to organic chemistry! It s not as bad as you heard! Summer class = major work
3 What is Ochem? Focus on carbon-based compounds Understand bonding in organic compounds Recognize functional groups and patterns based on them See molecules in 3-D and learn how 3-D differences affect behavior Begin to study reactions, looking for logic & patterns that govern tranformations
4 Yep, Cumulative Chemistry is alway cumulative G-chem --> 51A 51A --> 51B and so on... NOT ALLOWED = But that s from Gchem...
5 Gchem Topics Types of bonds/orbitals Electronegativity molecule shapes/polarity acids/bases equilibrium (general concepts) kinetics (general concepts) solutions/concentrations (lab) stoichiometry (lab)
6 How to Approach Ochem MEMORIZATION DOES NOT WORK!!! Critical thinking, logic, patterns Understand how & why
7 This Class Is Different! A different approach...no lecture Then what are we doing? Active learning Flipped or Inverted class
8 How It Works Read/watch lecture podcasts 2. Short reading/watching quiz 3. Class message board (optional) 4. In-Class activities 5. Online homework
9 Where to Find Stuff Class website: EEE for message board Sapling Learning (online HW)
10 Not a UCI Student? You MUST activate your UCInetID!!! Go Here: academic/ucinetid.aspx
11 Important Dates Quizzes: Mondays, July 2- July 23 Midterm: Wednesday, July 11 (class after!) Final: Wednesday, Aug 1, 9-11 AM
12 What s Up for Today? OMG! Test! Relax, it s a pre-test. I need to know what you know and don t know! It can t hurt your grade! How to approach podcasts & such G-chem topics review
13 Pre-Test Time 50 minutes All multiple choice Pencil, eraser only DON T WRITE ON EXAM!!!
14 Not Doing These Questions DON T WRITE ON THE TEST!!! Mark A on Scantron for these
15 Why the test? Study how well this method works Measuring your learning gains by performance on test now and at end EXTRA CREDIT OPPORTUNITY!!! Improve your performance on posttest by 75% or more and earn 10 POINTS EXTRA CREDIT!!!
16 How to Watch Podcasts? Active vs Passive Take notes Write down questions Try all examples Communicate on message board
17 Gchem Topics Review Atomic structure Electronic structure Bonding Periodic trends
18 Atomic Structure Which of the following statements is NOT TRUE regarding atoms? A. The identity of an atom is determined by the number of protons in the nucleus. B. Electrons travel around the nucleus like planets around the sun. C. An atom that has lost an electron is called a cation. D. An atom that has gained an electron is called an anion. E. The mass number of an atom is the sum of its protons and neutrons.

The mass number of an atom is the sum of its protons and neutrons.
20 Electrons and Orbitals Which of the following statements regarding electrons and orbitals is TRUE? A. Elements in the first row have both s and p orbitals. B. For a given energy level, a p orbital is lower energy than an s orbital. C. s orbitals have two lobes. D. The second shell can have a maximum of 10 electrons. E. Each orbital can hold up to 2 electrons.
21 Electrons and Orbitals Which of the following statements regarding electrons and orbitals is TRUE? A. Elements in the first row have both s and p orbitals. B. For a given energy level, a p orbital is lower energy than an s orbital. C. s orbitals have two lobes. D. The second shell can have a maximum of 10 electrons. E. Each orbital can hold up to 2 electrons.
22 Remember Orbitals?
23 Bonds Choose the correct statement. A. Atoms attain a complete outer shell of valence electrons by bonding with each other. B. In an ionic bond electrons are shared between atoms. C. Covalent bonds occur between metals and other metals. D. Bonding between atoms leads to higher energy and less stability. E. In a covalent bond electrons are transferred from an atom of one element to an atom of another element.

27 For Next Class... Watch these podcasts: Lewis Structures Lots of review here! Bonding & Geometry Drawing Organic Structures Acids & Bases And take the corresponding quizzes.
Do NOT rely on this as your only preparation for the Chem 101A final. You will almost certainly get a bad grade if this is all you look at.
