Homework Answers
1.We can not use methanol for extraction because methanol is water soluble, so while extraction we can not get two separate layers.
2. Extraction process is separation of organic and aqueous layer but if you use methanol as a organic solvent we can not get layer separation, so we can not use methanol in palce of dichloromethane.

Steps for the separation by extraction of benzil? What order of steps do I need to place it in? Describe the procedure for the separation by extraction of the neutral compound, benzil, from the basic compound, p-chloroaniline. Both compounds are soluble in dichloromethane and insoluble in water. At the end of the prodecure, you must have solid benzil and solid p-chloroaniline separated Note: dichloromethane is a highly volatile solvent, thus if you boil a solution of a compound in dichloromethane...

We used the technique of extraction in this lab. After extraction, what was left in solution? Why is it acceptable for those chemicals to be left to sit for a week? Think about the possible reactions that would or would not occur during the week? In our extraction, we used NaCl solution. Why did we choose to use that vs. water? In this experiment, we did a Fischer Esterification using excess acetic acid, isopentyl alcohol, and sulfuric acid to form...
