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!

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

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?

I need some help with an alkene bromination lab. These are the directions: For this assignment, the target compound that you should synthesize is anti-2,3-dibromo-butane. This is a stereospecific electrophilic alkene addition reaction. Examine the product to determine the location of the new functionality. Keep in mind the bromonium ion intermediate and the consequences of its structure. The nucleophile again attacks in a manner that controls the stereochemistry of the product. ----------------------------- ***I need to know what materials, solvent, and...
