Safety
You are expected to abide by the safety rules outlined in the Lab Safety Agreement.  Your health and life, as well as your grade, may be greatly affected by not doing so.
Any safety violation  will result in a loss of  5 points. Repetitive (3) violations may result in a failing grade for the  lab.

Work organization
It is crucial for you to be prepared for the lab each week. This entails reading the required material (the experiment as well as the techniques) in advance and preparing the procedure in the notebook. You are not allowed to use a textbook in the lab!!
Please organize your work in such a way, so that you were finished with the experiment and clean-up by the end of the scheduled lab period. Glassware must be cleaned and dried and the hot plate allowed to cool  at the end of each lab period. Plan to spend about 20 minutes doing this.
The experiments are designed so they can be completed in the time allotted. It may happen that you will finish earlier if you are prepared. However, do not schedule work or other classes during the four hours assigned to this class.

Grading
Your grade is a compound of the points  received for a laboratory notebook and the weekly quizzes. The grade is assigned based on the following percentages:
   Lab notebook    67%  (20 points)
   Quizzes   33%  (10 points)
Quizzes are given within the first 15 minutes of the lab session and will pertain to the experiment conducted the previous week and to the required reading for the experiment to be conducted during the current lab period.
Students who arrive late will only have as much time to finish the quiz as is left of the assigned 15 minutes.

Reports
Reports (lab notebooks) are due the following week at the beginning of the lab period, before the quiz.
Only one late report will be accepted with no loss of points. The second one week late report will result in deduction of 6 points. Any reports that are more than one week late will not be accepted. The consecutive late reports  will not be accepted.

Glass breakage/care
The glassware used in this laboratory is extremely expensive. Common sense will definitely prevent breakage. Please read carefully  the section in your lab manual about  the care and use of glassware.

Breaking a piece of glassware from either a semimicro- or macro kit, or a thermometer will cost you  three (3) points per item.
Remember that you share the equipment with other lab sections.  Not cleaning the glassware after the experiment will also result in the loss of two (2) points.
 
 

Organic Chemistry Laboratory Notebooks

Laboratory notebooks will be graded based on the following criteria:

Format ( 2 points)
Standard lab notebook with carbon-copy pages, available in the bookstore should be used. All write-ups should be in permanent ink. Notebook should have a table of contents and  pages should be numbered consecutively.
Each report should begin with a title, date and the partner’s name (if any).
The procedure, discussion and postlab answers should be placed on the left-hand side of the page.
The right-hand side should be used for data, calculations and observations only.

Each report must contain  the following sections:
- Introduction (2 points) In your own words, state briefly what the experiment is about. Include reactions and mechanisms, if known, and any physical data needed for the  experiment (density, molecular weight, melting and boiling points, etc.).

- Procedure (3 points) Write the procedure that will be followed. It should be written in such detail, so that you could duplicate the experiment using a notebook only (no text books are allowed in the lab!!!!). Therefore, pictures or drawings of  the equipment set up should be included as well.
The procedure MUST be written before the lab, but should be amended afterwards if  any  additional details are necessary.
It is acceptable, but not encouraged,  to make  copies of the procedure and pictures   and paste them onto the notebook page.

- Observations and Data ( 3 points) This section should include any observations made and the data (e.g. weights/volumes of reagents and  products) acquired during the experiment.
 

- Results and Discussion ( 6 points) Discuss in detail and interpret your results, including   any IR, GC or GC/MS analyses. Show all calculations (on the right hand-side of the page). Give results of the calculations, including yields. If your results are           different from those expected, include plausible explanation for the deviations.
Remember, even if your experimental results are unexpected or incorrect (e.g. low or no yield), you can still receive most  or all of the results and discussion points, as long as you reasonably explain where or how the errors occurred. This is why careful and detailed observations and note taking are necessary during the experiment.

- Questions (4 points) Answer all the postlaboratory  questions from  the book. Include explanations and, if applicable, calculations.

The original copies of lab reports  are turned in to the instructor. The carbon copies will be left in the notebook as your record of the experiment.
