*Heading & Title (1 pt) – Your name, your lab partner’s name, date, course section, TA’s name, name of the experiment *Purpose (1 pt) – The reason for the experiment in your own words; 1-2 sentences.
*Reaction & Physical Properties Table (4 pt) – Draw the reaction (if you’re performing a reaction) and record the physicals properties (mp, bp, MW), including units, of the reactants, reagents, and products you will use or make. Reactions are drawn using a program like ChemDraw.
*Safety (4 pts) – Any safety precautions necessary for the experiment should be outlined here. Examples include proper techniques (e.g. – for using syringes, for handling hot glassware, etc), a listing of chemical hazards, a listing of physical hazards, how to dispose of waste properly, and any other safety issue you see or your TA expects you to address. Make it a habit to reference all necessary chemicals’ safety information before handling them in lab. A good website to reference for this data is www.sigmaaldrich.com. You can search for and select the chemical in question, then click on the “Safety & Documentation” link.
*Procedure (4 pts) – A detailed explanation of the lab in your own words. You should be able to perform the lab by just following this procedure. This can be written as steps (e.g. – 1. Add 0.15 g of benzophenone to a 3 mL conical vial). Don’t copy from the lab manual. Don’t use personal pronouns (I, me, you, us, etc…)
*Data/Observations (4 pts) – Any colors, measurements (weights before and after), reaction times, etc. observed during lab. All graphs tables, and spectra must have a title and be clearly labeled. All IR spectra must have the functional group’s peak labeled. Record any and all observations. Draw pictures. Duplicate pages of your notebook & IR spectra should be attached to the back of the final lab report.
*Calculations & Results (5 pts) –You may or may not have calculations; usually this will be the weight and % yield (see below). Record all weights & measurements to the 2nd decimal place.
*Conclusions/Discussion (7 pts) – Discuss the results of the experiment thoroughly and in at least 4 full sentences. This should include a brief description of the lab, its purpose, and state why the lab was or was not successful by citing specific data collected during the experiment. You must reference your results in this paragraph, the actual weight of your product, the percent yield (if applicable), peaks observed from IR spectra, etc… One should be able to read just this section and get all the pertinent data from the lab.
*Post Lab Questions (10 pts) – Answer all assigned post-lab questions
You may use your own numbers/results (make sure the made up numbers make sense for the experiment)
