Text:                             Organic Chemistry Laboratory Lab Manual

 

This is the second semester of a two-semester sequence in the manipulations involved in organic chemistry.  Be sure to continue to take proper care of your equipment, keep your work area clean, and exercise proper care of the chemicals and the community equipment such as melting point apparatuses. 

 

Professional Behavior:  You are expected act in the following manner while in the laboratory

1)  Observe all safety rules.  That is, neither food nor drink is allowed in the laboratory.

2)  Safety glasses are required at all times.

3)  Your work area is to be kept clean at the end of your laboratory period.

4) Your samples must be submitted with a label that tells the product, per cent yield, raw yield, and mp or boiling point.

5)  Honesty is worth more than a good report.  Dishonesty and disregard for laboratory equipment will result in expulsion from the laboratory.

 

Failure to observe rules 1 and 2 will result in expulsion from the laboratory

Failure to observe rules 3 and 4 will result in a loss of 10 pts for each violation.

 

You will be graded on the percent yield of your products as well as the purity of your product.  You must be careful in the organic lab.  The goal of the lab is not to “get done as fast as I can” but rather to learn about organic chemistry.

 

Tentative Schedule. 

 

 

Week of                                               Experiment

04/18-04/222               Final Exam,

             

 

Again, students must adhere to the safety guidelines and little tolerance will be given since you are now in your fourth semester of chemistry labs.  No food or drink in the lab, eye protection must be worn, and no shorts or sandals are to be worn in the labs. Sloppiness will not be tolerated and your work station must be cleaned when through with the lab period.

 

Grades are as follows:              

10 labs @ 50 pts each = 500 pts          Grade: attendance = 10; product = 30, write up = 10   

 drop one lab score         -50 pts

One Final Exam               100 pts

                                       550 pts total                 

495 – 550 =     A,

440 - 494 =     B,

385 - 439 =     C

<385        =      D
