Organic Chemistry Formal Lab Report Text

Jonathan Friesen - Writing Coach

Writing an organic chemistry lab report components of a laboratory notebook the following components should be contained for each experiment, along with any additional material required by your instructor. Title and date introduction purpose, reaction in a sentence or two, state the purpose of the experiment. If the experiment is a preparative experiment, the introduction also includes the balanced equation for the reaction. In organic chem, there are different types of experiments: technique and preparative. A technique experiment is one in which you are performing a technique for the first time and studying its details, for example, distillation and extraction. A preparative experiment is one in which a compound is synthesized from other reagents. Physical data laboratory reports the graded components are: the scores you obtain for laboratory reports and laboratory performance constitute 50% of your grade, and as such form the foundation for your laboratory grade.

However, we expect many students to work carefully in lab and complete well written reports on time and receive similar grades on this part of the course. The scores on quizzes and the final examination often vary more widely and thus are often the basis for differentiation between a, b, and c grades. However, if you do not do a good job on your laboratory reports, it will be difficult to receive a high grade in this laboratory course. The following guidelines are offered to assist you in writing up satisfactory laboratory reports. Although we are not using formal, bound laboratory notebooks, proper record keeping practices should be used for lab reports. Therefore, all entries in the report itself not necessary for pre and post lab questions should be made in ink. If you make a mistake, cross through the incorrect material it should still be legible and record the correct information.

Don rsquo t record information on other paper with the intent to transfer the information to the report except for weights obtained at the balance. Always transfer the information immediately to your reports section after returning to your workstation. The pre laboratory questions that you download from the organic website constitute 5 points of the laboratory report. These questions are designed to make you think about important concepts covered in the experiment.

These questions must be completed before the start of the pre laboratory presentation in room 255 and turned in to the appropriate box at the front of the room. To receive full credit for the pre laboratory questions you should turn them in prior to the pre laboratory presentation. The first page of the laboratory report must be completed before you start the experiment.

Some of the information necessary to complete this portion of the report may require you to access reference texts or reference materials on the internet. Therefore, you need to complete this part of the report before the day of your lab period. Do not try to complete this part of the report while sitting in the pre lab lecture room. The purpose of the pre laboratory questions and of the pre laboratory write up are to encourage your study of the entire experiment prior to coming to the laboratory period. This time spent prior to the laboratory period will result in a more enjoyable, rapid lab experience.

The objectives for most of the experiments are given in the experiment descriptions in the lab manual or on the web pages. You should include a reference to the location of the detailed information lab manual pages or handout titles describing this laboratory experiment. The experimental procedure should not be a verbatim copy of the detailed procedure given in the lab manual or handout. It should include a synopsis of the detailed procedure that clearly states the steps that should be performed so you can use it to perform the in the correct order during the lab.

This section should include equations for all organic reactions in experiments that involve specific reactions syntheses, classification tests. The table of reagents is quite important and may require space on an additional page for some experiments. The important reagents and solvents should be listed along with the properties that are important in the experiment. For synthetic reactions, the molecular mass of each reagent and product in the balanced equation is necessary in order to determine limiting reagent and to calculate theoretical yields see page 2 of laboratory manual. The density of a reagent is needed if the procedure calls for addition of a specific volume rather than a weight.
