How to determine which layer is which?
Select one:
a. Two immiscible solvents will stack atop one another based on differences in density.
b. Two immiscible solvents will have two different color
c. The Organic Layer Is Usually On The Bottom And The Aqueous Layer Is On The Top In The Separatory Funnel
d. Add more pure solid organic compound to the Separatory Funnel
e. The Organic Layer Is Usually On The Top And The Aqueous Layer Is On The Bottom In The Separatory Funnel
Homework Answers
If we know the density of two given immiscible liquids , then liquid with less density will be on the upper layer .
Option (a) is correct.
Teo immiscible solvents will stack atop one another based on differences in density.
Ether have less density than water , so upper layer is of ether and lower layer is of water .

Answer the following before coming to lab: 1.) Based on what you saw last week, which enantiomer of tartaric acid would you expect to co- crystallize with (SS)-1,2-diammoniumcyclohexane? 2.) If you had a neutral aqueous solution of triethylamine, would you add acid or base in order to extract it with an organic solvent? 3.) Now, consider a dichloromethane solution of triethylamine. Would you extract with acidic aqueous or basic aqueous solution in order to get the triethylamine out of the...

Hello, I need help understanding a lab we are doing in class tomorrow. I need to know which is the "ORGANIC LAYER" ... we are using a separatory funnel, and I would like to know whether the organic layer will be on top or on the bottom. This is in order for me to correctly carry out the experiment. The lab is similar to this one I found online, and its very vague for me as to what is the...

Just Answer Question 5
Synthesis of 2-chloro-2-methylbutane (literature version) Concentrated aqueous hydrochloric acid (HCI, 3.3 equivalents) was slowly added to 2-methyl-2-butanol (1.0 equivalents) in a 100 mL round bottom flask with stirring. The reaction was stirred for 15 minutes at room temperature. Upon completion, the reaction mixture was transferred to a 60 mL separatory funnel and the aqueous layer was removed. The organic layer (i.e. the product) was successively washed with: (1) saturated aqueous NaCl (brine), (2) saturated aqueous NaHCO,...
