May 12, 2021 · Data and Results: The purpose of this lab is to observe the reaction of 9-fluorenone to 9-fluorenol through reduction via a reducing agent, sodium borohydride. Mixed-solvent recrystallization is used to purify the product before it is analyzed utilizing infrared spectroscopy and melting point to confirm the identity of the product after obtaining its mass …
Abstract. The Abraham solvation parameter model is used to calculate the numerical values of the solute descriptors for 9-fluorenone, thianthrene and xanthene from experimental solubilities in organic solvents. The mathematical correlations take the form of log C S C W = c + e E + s S + a A + b B + v V log C S C G = c + e E + s S + a A + b B + l L where CS and CW refer to the solute …
May 25, 2005 · Zdanowicz and Strauss [29] reported a value of 8.02 × 10 −5 M (log CW = −4.096) for the solubility of 9-fluorenone in an aqueous 0.1 M LiCl solution. Dissolved salts generally decrease the aqueous solubility of organic compounds (the so-called “salting-out effect”).
See the answer See the answer done loading. 1. Draw the chemical structure of 9-fluorenone and use it to answer the following solubility-based questions: a) Circle and label all regions of the molecule that exhibit non-polar behavior. b) These non-polar regions interact with solvent molecules with what types of intermolecular forces (list all that apply): hydrogen bonding, …

So why is fluorenone insoluble in water? Because even though fluorenone is polar (like water), the non-polar aspects of the molecule repel water molecules, making it unavailable for forming a solution with water.

The color appears yellow at the beginning because of 9-fluorenone. Then it is reduced and all the other reactants are colorless so it becomes colorless as well.
Since diethyl ether is nonpolar, 9-fluorenone, which is also nonpolar will dissolve better in diethyl ether than in the aqueous (polar) phase.
9-fluorenone has one polar C=O. bond, but it also has two aromatic rings. Dispersion interactions are strong for such aromatic rings, and the point can be made that this factor will drive the solvation of 9-fluorenone in hexane. This is confirmed by the fact that 9-fluorenone is insoluble in water.May 8, 2020
Chemical Propertiesyellow flakes, chips or crystalline powder; Soluble in ethanol and ether, insoluble in water. 9-Fluorenone has been extensively used as a precursor to synthesize a variety of organic electronic materials.
Fluorenone is more polar than fluorene because of its C=O. bond. Fluorenone's spot will be lower than fluorene because of its "stickness."
Benzoic acid, Ethyl-4-aminobenzoate, and 9-Fluorenone will be the compounds used to separate into their pure components. Of these compounds, they are all considered organic acids and bases and neutral organic matter.Dec 6, 2019
The percent recovery for 9-Fluorenone was the least because it did not involve filtration using a Hirsch funnel, but rather it was heated to remove the ether solution from the substance. Despite this, the percent recovery was still above 100% due to remaining ether that had not evaporated.May 18, 2020
9-Fluorenone is used in the preparation of antimalarial drugs. It is a fluorene derivative. Further, it is used in functional polymer and in dyes. Soluble in water, alcohol, acetone, ether and benzene.

The Abraham solvation parameter model is used to calculate the numerical values of the solute descriptors for 9-fluorenone, thianthrene and xanthene from experimental solubilities in organic solvents.
This work continues a systematic application of the Abraham solvation parameter model for describing the solubility behavior of both inert and self-associating solutes dissolved in neat organic solvents of varying hydrogen-bonding characteristics.
9-Fluorenone (Aldrich, 98%), thianthrene (Aldrich, >99%) and xanthene (Aldrich, 98%) were recrystallized several times from methanol. Water (Aldrich, HPLC) was used as received.
The applicability of the Abraham solvation parameter model is relatively straightforward. The logarithm of the solubility ratio, log ( CS / CW ), is calculated for each organic solvent for which we have process coefficients and experimental solubility data. For select solvents both “dry” and “wet” process coefficients have been reported.
the solubility of silver sulfate in water is 0.223% (w/v) at 35 degrees celsius.calculate the solubility product of this salt at this temp. I got 1.46 X 10^-6 M is this right please thanks Andy
I know the solubility of PbF2 is pH dependent because the solubility would increase as the solution becomes more acidic because the F^- ion is
