Draw a picture of a separatory funnel with an aqueous layer and a dichloromethane layer. label each layer. which of the two layers would contain eugenol?

Why is the drying agent added to the dichloromethane layer after extraction?

why is steam distillation used to isolate the eugenol from the cloves?

A. Draw a seperatory funnel with isopropyl acetate and aqueous solution in it. Label the layers. Which is the top and which is the bottom and why is this so? What property of each liquid determines if it will be the top or the bottom layer. B. What properties of the compounds is this separation based on? Which of the two (Benzoic acid and ethyl-4-hydroxybenzoate) is more acidic? C. Which of the two compounds is extracted into the aqueous layer...

4-bromobenzoic acid (1.0 g) is dissolved in 20 ml dichloromethane. After addition to a separatory funnel, the dichloromethane solution is treated with 20 ml 3.0 M NaOH solution. After the layers are separated, which layer(s) will contain an organic compound (non-solvent)? What would happen if the aqueous layer is treated with 20 ml 3.0 M HCl?

Draw a picture of a cell located in the intestines for yourself and label the surfaces and draw the location of the different receptors found on the plasma membranes. Then explain in your own words to turn in all of the different carrier proteins involved in the reabsorbtion of sodium and glucose from the intestinal mucosa to the blood. What is the functional significance of tight junctions? Reflect on the fact that this is the same system involved in the...

In lab we did a liquid-liquid extraction using a separatory funnel - but i don't really understand what was happening ( i just followed directions given) - now my lab report asks me to describe 1. the concept of liquid liquid extraction and how it works 2. Describe how adjusting the pH of the aqueous phase as a means of altering solublity properties of compounds is used in extractions?? can anyone help me understand these two questions above.

I need to prepare 2-bromopentane from H2SO4, NaBr, and 2-pentanol using reflux, a separatory funnel, and possibly distillation. My question is if this is the right procedure and if I will get a good yield. Amount of 2-pentanol cannot be changed in the procedure. The apparatuses listed in the procedure are the only ones available. The only possible washes are water and NaHCO3, and only sodium sulfate is available for drying. I am questioning whether I need to distill before...
