The Lab Report should include the information listed below, in the order given. Include a heading for each section, so that the report looks professional. All Tables should use the Table formatting feature in Word (or other software) including horizontal and vertical lines. The yield calculation should use the equation editor in Word. Structures should be drawn using ChemDraw as skeletal line structures or when possible, condensed notation (CH3CH2OH) . Dont use condensed structures for substituted aromatic rings. Note that you will be graded on grammar, organization, and composition (15 pts). Give yourself plenty of time to write this report and use your lab notebook to help you recall what you did and when during the experiment. Your report should be uploaded as a docx or doc file here. Do not email the report to me; only uploaded reports will be graded. Remember 20% is deducted for every 24 hours the report is past due.
1.Title of Experiment (4 pts)
2.Dates performed (3 pts)
3. Your full name and lab partners name (be sure it is clear who is the author of the report vs the lab partner), (3pts)
4. Main Reaction Equation (Use ChemDraw ). Be sure that you include all reagents used, including the solvent, which are often written above the reaction arrow. (10 pts)
5. Data Table (as given in hand-out, but use normal table format, and make it clear which is a reactant and which is the product. The table should contain a column with the mass or volume of material used, molecular weight (molar mass) of everything but the solvent, moles of starting material and reagents used (be sure you know how to calculate moles (using density if a pure liquid, using molarity if a solution, or mass of a solid). (15 pts.)
6. Procedure: Write the procedure you actually performed to conduct this experiment. Write as as though it were being submitted for publication; in other words, use complete sentences, avoid slang, use paragraphs, and proofread your work. Remember to avoid the first person (I did this
, we did this
) and write in the past tense. For example: To a 50 mL Erlenmeyer flask was added 5.0 g of methanol
.Please, please proofread your work before submitting; read it aloud to yourself or someone else and see if it makes sense (missing verbs, run on sentences, parallel structure). It is ok, and even a good idea, to have someone else also proofread your report. Remember to use and spell technical terms correctly, ie reflux, vacuum filtration. (20 pts)
7. % Yield: Since your product samples dissappeared, you will not be able to calculate a yield using the actual mass you recovered. Instead, assume a hypothetical recovery of 50.0 mg of product. Show your work, ie, how you calculated the theoretical moles and actual moles, and the % yield. Use the math editor in Word. Remember also that the yield is not a reflection of the purity (5 pts.)
8. Melting Point Table: Since your product samples dissappeared, just provide the literature value of the melting point of the product. Explain what the following scenarios mean: a) the melting point is sharp (ie melts across a narrow range) and is close to the literature value; b) the melting point is depressed (lower than the literature value) and melts over a wide range. (5 pts)
9. IR Analysis: Compare the differences between the IR of the starting material and the IR of the product using the IR spectra in this folderprovided by two students in the class (5 pts.)
10. Conclusion: Explain how you were to determine the structure and purity of the product you prepared. (5 pts)
11. Give yourself plenty of time to do this step: Show the mechanism for the formation of the t-butyl cation (SN1) and the mechanism for the electrophilic aromatic substitution. Use ChemDraw for the mechanism using the double headed normal mechanism arrows. (10 pts)
Organization and Clarity of writing: 15 pts
