Unformatted text preview: 8/15/2011 1 HUNTER COLLEGE -- DEPARTMENT OF CHEMISTRY CH E M 223 -- Organ ic L aboratory I Welcome to the CHEM 223 Lab! NOTE: STUDENTS REGISTERING FOR THIS LABORATORY COURSE MUST ALSO REGISTER FOR THE ACCOMPANYING RECITATION CHEM 223RC. Recitation attendance is mandatory for any student enrolled in the lab and a significant portion of the course grade for the CHEM 223 lab comes from exams given in the Recitation. Text: The laboratory text for CHEM 223 is Pavia, Kriz, Lampman, and Engel: A Small Scale Approach to Organic Laboratory Techniques Third Edition . COURSE DESCRIPTION AND GRADE ASSIGNMENT The first part of the course teaches you how to separate and purify organic compounds. You then synthesize a number of organic compounds yourself and employ the techniques you have learned (as well as some new ones) to separate, purify, and study your reaction products. Your grade will be assigned on a 1400-point schedule, which will be explained to you by your teacher. Your point total will be based upon recitation examinations, in-lab quizzes, laboratory technique, the products you hand in, the organization of your work, your write-up of experiments, safe lab practice, cleanliness, how well you have planned your work beforehand, and how well you understand the chemical processes that occur. When you hold a flask in front of your instructor to ask a question about the contents, you must be able to describe exactly what you put in the flask, and the exact sequence of operations you have carried out in arriving at that point. Your lab instructor will not simply provide answers You should always be prepared to intelligently discuss what you are doing and try to arrive at a solution to your own problem rather than rely on your instructor to solve all of your problems. PLANNING You must do quite a lot of preparation before you do the first experiment. Read pages 1-39 of the text with care. In addition to reading the text, you must attend the lab recitation and view the lab video (see below) for the first experiments . Take clear notes in the lab recitation and review them carefully when planning each experiment. The pre-laboratory assignment for each experiment 8/15/2011 2 must be completed before coming to class. Many of the experiments are not taken from the book, but Part Two (pages 588-823) contains descriptions of the techniques you will use throughout the term. The importance of studying the recitation material and applying what you have learned cannot be exaggerated. The text serves as a reference for both the recitation and the laboratory. In this first semester organic chemistry laboratory you will plan your work more independently than in previous laboratory courses. Students will work individually some experiments, but there are some procedures that you will perform in pairs. One set of equipment will be issued to each person. The key to success is planning your work carefully before you enter the laboratory! The person....
