Synthesis of a Fragrant Ester from Carboxylic Acid and Alcohol - Chemistry Assignment Help

Assignment Task :

Post-laboratory questions  
1. Draw the mechanism for the formation of your ester from the unknown alcohol and acetic 
2. In the experimental procedure, at the end of the reaction, you are asked to cool the round-bottom flask and its contents to room temperature before adding 20 mL ether to the reaction mixture in the round-bottom flask. Why must the reaction mixture be cooled before ether is added?
3. How does the IR spectrum of an ester differ from the IR spectra of a acetic acid and your alcohol?
4. Calculate the theoretical yield of your ester for 3.00 g of your unknown ester?
5. Using structures and electron pushing arrows, explain fragmentation pattern in the following mass spectrum of an ester.  Mark and Label molecular (parent) ion peak and base peak.  Write the mechanism for the formation of base peak and other two peaks of interest.
