I need help with an organic chemistry lab. The main topic is Ester Hydrolysis.
I start with 1,7-Dimethylhaptanedioate and water (solvent), and add the catalyst H2SO4. The reaction mixture is extracted with water. The final product is heptanedioic acid.
I need to know the steps of the reaction mechanism, as well as the role of each component in the reaction. I also need to know why the reaction mixture is extracted with water, and what the water does. Why water and not something else?
Thank you!

I need help with a 2-part organic chemistry lab. The main topic is esterification of fatty acids. In the reaction, I mix acetic acid, ethanol, and diethyl ether (solvent) together and then add the reagent (H2SO4) to the flask. The final product of this reaction is ethyl acetate. Ethyl acetate is then extracted in a separatory funnel using NaOH. For this reaction, I need help with 2 things. I need help with the overall reaction mechanism, and in identifying the...
Fundamentals of Organic Chemistry Lab Can you use melting point as a method of analysis for your ester? Explain why. 3. 4. What is the proper way to smell the esters you synthesize? 5. If you heat the reaction mixture after adding water, what will happen? Combinatorial Chemistry: Ester Synthesis In today's lab, you will perform small scale Fischer esterifications to make a variety of esters. H2SO4 +R'OH Он OR R R Combinatorial chemistry is a term used to describe...

Fundamentals of Organic Chemistry Lab Post-Lab Questions 1. If you were doing these experiments on a larger scale, describe two ways that you could improve the yield of the target ester What is the point of adding sulfuric acid to the reaction? How about the heat? 2. Pick your favorite of the esters you made, and write the mechanism for its formation. 3.

Combinatorial Chemistry: Ester Synthesis In today's lab, you will perform small scale Fischer esterifications to make a variety of esters. H2SO4 R OH + R'OH = ROR Combinatorial chemistry is a term used to describe small scale reactions, where in a large number of different molecules can be made using the same reaction conditions, by varying the reactants. In the case of Fischer esterifications, one can vary the carboxylic acid and keep the alcohol constant or keep the carboxylic acid...
Experiment #6 Ester Synthesis PRE-LAB ASSIGNMENT This pre-lab assignment is worth 5 points for this Experiment and should be completed on a separate page and turned in at the beginning of lab. 1. Read the experiment carefully 2. Safety Considerations: Summarize O safety and health hazards for working with glacial acetic acid, butanoic acid and petroleum ether. 3. Procedure: Summarize the procedure using a bullet list. Assume you are summarizing the procedure to a fully qualified chemist, i.e. don't include...
Organic chemistry -Carboxylic acid homework
Question: In the general chemistry lab, students synthesize
aspirin from salicylic acid and acetic anhydride. In the lab,
students use sulfuric acid as a catalyst, but I want to consider an
alternate method for synthesizing aspirin using sodium acetate as a
catalyst:
a. Draw the structure of sodium acetate. Is sodium acetate a
stronger or weaker base than sodium hydroxide (NaOH). Explain. (1.5
pts)
b. Consider the structure of salicylic acid. It contains two
potentially...
I need help forming a hypothesis for a formal organic chemistry lab report. My TA stated that it's better to construct it not like a typical hypothesis statement ( If...then..). How would I do that and can you give examples of some? I've been going back and forth on trying to create it and if it helps the report is over the Wittig reaction...
In Organic Chemistry II for the 'Preparation and Properties of Soap' lab, please help answer the following questions; 1. Write out a step-by-step mechanism for saponification. You may begin with a simple ester such as ethyl acetate. 2. The experimental procedure directs you to generously lubricate (grease) the ground glass connection between the 10 ml r.b flask in which saponification is being carried out and the reflux condenser. Why is this generous lubrication needed?
You are working in a chemistry lab that makes food additives and you are tasked with preparing 9.50 grams of butyl acetate for candy production. You know that esters can be prepared using Fischer esterification, and so choose to use that method to synthesize your target compound. Your reaction mixture is set up as follows: Add the alcohol (1.0 equivalent), carboxylic acid (1.3 equivalents) and H2SO4 (0.35 equivalents) to the Erlenmeyer flask. (Note that H2SO4 is an 18 M solution)....
