Chem 51A Dr. Link
Welcome! Welcome to organic chemistry! It s not as bad as you heard! Summer class = major work
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
Yep, Cumulative Chemistry is alway cumulative G-chem --> 51A 51A --> 51B and so on... NOT ALLOWED = But that s from Gchem...
Gchem Topics Types of bonds/orbitals Electronegativity molecule shapes/polarity acids/bases equilibrium (general concepts) kinetics (general concepts) solutions/concentrations (lab) stoichiometry (lab)
How to Approach Ochem MEMORIZATION DOES NOT WORK!!! Critical thinking, logic, patterns Understand how & why
This Class Is Different! A different approach...no lecture Then what are we doing? Active learning Flipped or Inverted class
How It Works... 1. Read/watch lecture podcasts 2. Short reading/watching quiz 3. Class message board (optional) 4. In-Class activities 5. Online homework
Where to Find Stuff Class website: http://sites.uci.edu/chem51asummer11/ EEE for message board https://eee.uci.edu/myeee/ Sapling Learning (online HW) https://www.saplinglearning.com/

Important Dates Quizzes: Mondays, July 2- July 23 Midterm: Wednesday, July 11 (class after!) Final: Wednesday, Aug 1, 9-11 AM
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
Pre-Test Time 50 minutes All multiple choice Pencil, eraser only DON T WRITE ON EXAM!!!
Not Doing These Questions 1 34 50 2 39 51 5 42 53-70 6 43 7 44 15 45 19 46 24 47 30 49 DON T WRITE ON THE TEST!!! Mark A on Scantron for these
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!!!
How to Watch Podcasts? Active vs Passive Take notes Write down questions Try all examples Communicate on message board
Gchem Topics Review Atomic structure Electronic structure Bonding Periodic trends
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.

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.

Remember Orbitals?
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.
