CHEM 244 - Organic Chemistry II Worksheet “Zero” (CHEM 243 Review) The purpose of this worksheet is to review a few key concepts from CHEM 243, Organic Chemistry I. The strategies you use to solve these problems will be essential for solving related problems in Organic Chemistry II. Here are your goals in completing this worksheet: • To complete this worksheet you will work with other students in class, along with help from Dr. Brush and the Peer Leaders. It is also expected that you will work on your own outside of class. • You may want to watch the “Mechanism Review” video on the class web page. • Review the “Substitution/Elimination Guide” attached to the end of this worksheet. • As needed, review lecture videos from CHEM 243. • Make a list of any questions you have, and make sure that these get answered! The Peer Leaders and I love being asked questions! You can continue asking us questions next week. • You will not turn this worksheet in. However, your target date for completion is Friday, January 28. • To get credit for this work, you will need to click this link and complete a class survey no later than 5:00 pm on Friday, January 28. DON’T FORGET!!! By completing this survey you will earn 50 points that will be “Banked” and used to replace your lowest Group Quiz grade. PART I. Read the Syllabus. In the survey you will need to confirm that you have read the class syllabus and understand the expectations for this course. PART II. Class Project. As part of our normal class work we will explore the problem of global warming, understand the challenges of institutionalized environmental racism, and learn how green chemistry can contribute to reducing the impacts of greenhouse gases through carbon capture. As we learn new concepts in organic chemistry, we will apply these concepts to understand the background chemistry behind carbon capture. This project will focus on the chemistry behind the capture of carbon dioxide, and the reactions of CO 2 . (a) In the box below, answer the following questions related to bonding and structure in CO 2 : • Draw the best Lewis Structure for CO 2 • Include all relevant lone pairs • Indicate the hybridization (sp, sp2, sp3) of each atom • What is the molecular geometry of the carbon atom? • Total number of sigma covalent bonds _____________ • Total number of pi covalent bonds ______________ (b) CO 2 is formed in the combustion of fossil fuels. The combustion reaction of a hydrocarbon is given below. Put the proper coefficients in the boxes to balance this equation.
