Lab #: EXPERIMENTDatesDepartment of Chemistry 1 CHE 201 Organic Chemistry Microscale Lab Program–fall 2015 Lab director: Dr. Khalid Ahsan ([email protected]); Office: NSC 301; Phone: 645-4115 Office hours: Monday and Thursday 1-2 PM and By Appointment REQUIRED TEXTS AND MATERIAL 1) Lab Manual: Multiscale Operational Organic Chemistry: A problem solving approach to the laboratory course, by John W. Lehman, 4th custom edition for University at Buffalo, (2012). 2) Chemistry Notebook - Any bound chemistry Note book (or a composition book) can be used. Spiral bound notebooks or loose sheets in a 3 ring binder are not allowed. 3) Lab Materials: lab kit (same as CHE 101-2/107-8), monogoggle safety glasses, and a padlock for lab drawer are required (available at the bookstore). Proper protective clothing are required, long sleeve shirt, pants, and intact footwear covering the entire upper portion of the foot. You will not be able to work in the laboratory without proper clothing. Protective clothing is also detailed in the Laboratory Notes document available on UBLearns. Learning Outcomes and Objectives: Upon completion of CHE 201 laboratory course, a typical student should be able to: 1. Carry out experiment effectively and safely in the organic laboratory. 2. Perform micro scale reactions and synthesize organic compounds 3. Determine boiling point and melting point of product. 4. Perform purification of compounds by distillation, chromatography and recrystallization. 5. Identify products using boiling point, melting point and chemical analysis. 6. Take good experimental notes and data. 7. Write good laboratory report according to standard format of organic chemistry. 8. Develop good Team working and problem solving skills 9. Relate principles of chemical reactions and mechanisms to organic functional groups 10. Propose reaction mechanisms for common organic chemistry reactions IN THE LABORATORY Before starting any experiment A Laboratory Safety Quiz needs to be completed and students have to check-in and assume responsibility for all the assigned equipment. . A discussion of the theory, practice and methods will precede each experiment. These discussions will be held during the first hour of the lab period (recitation section). Please study the theory and familiarize yourself with the techniques required for all the experiments. Attendance of the pre-lab lecture and performance of each laboratory experiment is mandatory. A missed laboratory experiment cannot be made up at another time and any missed laboratory session will result in a grade of zero (0) for that experiment. Students who unavoidably miss a lab experiment must fill out and submit an excuse form (available on UB learns and Chemistry Copy Center NSC 361) within one week of their absence. STUDENTS WITH AN APPROVED ABSENCE* MAY BE EITHER ASSIGNED A MAKEUP ASSIGNMENT or PRORATED”. You can only be excused from lab if you a Valid excuse that can be documented.Please Note: Students who miss recitation WILL NOT be allowed to work on that lab and will receive a “0” for that lab. Lab Check-Out: All students must check out of their lab drawer during their regular lab period (with their lab instructor) during the week of check-out Nov 16- 21, 2015). Those who do not are subject to a $100.00 improper check-out fee plus charges for broken, missing or unusable equipment as well as having the lock cut off the drawer. (Safety glasses and lab kits will be held in the stockroom for one month only). Students who drop the course during the semester must check out within one week of dropping to avoid the lab check-out charge. Students who are absent from check-out at the end of the semester because of illness must complete a waiver form, available at the Copy Center (NSC 361) to have this $100.00 charge waived. This form requires written documentation from a physician verifying the reason for the absence. Lab Safety and Regulations: Personal lab safety is very important when working in a chemical lab. Failure to abide by these guidelines may seriously endanger you and your fellow students, and WILL NOT BE TOLERATED. Deductions from your lab grade will be made for any behavior on your part which is inappropriate in a lab, or for failing to clean up your lab space before you leave the lab. More details are provided on page 3 of this document. Grading Policy: The laboratory component of this course comprises 25% of the final course grade [250 max points].To remove any grading inconsistency, lab grades will be normalized at the end of the term. This will mean that the averages in some sections will be raised or lowered. Any Problems regarding the grading policy should be directed toward the Course Instructors or Dr. Ahsan, not to the teaching assistants. More details are provided on page 5 of this document. CHE 201 Lab Exam: Lab Final exam (multiple choices, short answers and reaction equations) will cover material discussed in recitation, assigned readings, and procedures as actually done in lab. Students are also required to know basic principles of organic chemistry for the exam. Details will be provided later.

The following is a list of safety guidelines that need to be strictly followed. i. DO NOT PERFORM ANY EXPERIMENTS IN THE LABORATORY UNSUPERVISED ii. Wear splash-proof goggles at all times. State and Federal law require the use of safety eyewear by anyone working in a chemical laboratory. The Department has approved splash-proof goggles for this purpose. These are available for sale in the Bookstore. iii. Wear Chemical resistant Lab apron at all times. State and Federal law require the use of Lab apron by anyone working in a chemical laboratory. iv. Contact lenses are not recommended. Students need to sign a contact lens waiver form if they have to use contacts. v. Wear clothing (shirt,
