The methylene chloride solution added to the developing chamber was a clear solution.
The fluorene added to test tube 1 was a fine white powder, and when dissolved in the
methylene chloride resulted in a clear solution.
The 9-fluorenone a
REVIEW OF IMPORTANT CONCEPTS FROM CHEM 345
In this unit we will review some important concepts that were covered in CHEM 345. The goal here is to make sure that you all have
a well-stocked organic toolbox and that you know how to use these tools to solv
The 9-flourenol was a white solid.
The methanol added to the graduated cylinder was a clear liquid.
When the clear concentrated sulfuric acid solution was added to the methanol, the
graduated cylinder became noticeably hot to the touch.
The mixture of the benzoic acid, ethyl-4-amino benzoate, and 9-fluorenone was a white
powder on top of a yellow powder
When dissolved it produced a light green/yellow solution
After adding the 3M hydrochloric acid, mixing, and venting, th
Dissolving the benzoic acid in the diethyl ether solution resulted in a clear solution after
stirring the mixture, which was poured in the separator funnel.
After adding 20 mL of 3M HCl to the solution in the separatory funnel and shaking
The 9-fluorenone was a yellow powder, and dissolved in the anhydrous methanol which
resulted in a yellow solution.
The addition of acetone to the fluorenone resulted in a yellow/green solution, and the
addition of acetone to the fluoren
Mixing the absolute ethanol with the aqueous sodium hydroxide resulted in a clear liquid
The benzaldehyde and acetone mixture was also a clear liquid
Adding the benzaldehyde and acetone mixture to the ethanol/sodium hydroxide mixture

1. TLC is used to monitor reaction progress and identify unknown compounds, while liquid/
liquid extraction is just to separate mixtures based on their solubility. TLC can tell us
substance purity or compare substance po
Post Lab Questions:
1. Water is more polar than diethyl ether because the difference in electronegativity
between C-O bonds is less than O-H, making the bonds in water more polar.
2. When the pH of the solution is changed from basic to neutra
Lab 2: Extraction of a Three Component Mixture
Post Lab Questions:
Benzoic Acid: 4.21
2. The higher the pKa of an acid, the weaker the acid the more tightly it holds on
