Is 9 Fluorenone polar or nonpolar?

Is 9 Fluorenone polar or nonpolar?

Is 9 Fluorenone polar or nonpolar? Overall, fluorenone is a polar compound, mainly due to the presence of the ketone. Since oxygen is more electronegative than carbon, there is an unequal sharing of the electrons in the form of the double bond, making it polar.

? 9-fluorenone has a polar C−O bond.

? benzoic acid is more polar than 9-fluorenone.
Also, when considering solvents you must remember that “likes dissolve likes”.
However, in this experiment we didn’t want the compounds to be too soluble in the solvent because we didn’t want them to dissolve at room temperature.

? 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.
9-fluorenone is not acidic or basic in water, and in insoluble in aqueous solutions.

What does hexane look like?

N-hexane is a clear colorless liquids with a petroleum-like odor.

So why is fluorenone insoluble in water


This is so that the acidic component is separated from the neutral component which is soluble only in the ether solution.
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.

Is ferrocene more polar than Acetylferrocene?

Ferrocene is less polar than acetylferrocene. Ferrocene moves on an alumina gel column using hexane as the eluting solvent, but acetylferrocene will not move from the top of the column with hexane. The ferrocene elutes first (with the hexane) and then the acetylferrocene elutes (with the methylene chloride).

What is the best solvent for recrystallization of fluorene?

Since fluorene is quite nonpolar, a polar solvent is the best bet for crystallization. Since fluorenone is somewhat polar, nonpolar solvents are likely to be good choices for crystallization. Fluorene: Ethanol is a good choice.

Is fluorene neutral?

It is insoluble in water and soluble in many organic solvents.
Although sometimes classified as a polycyclic aromatic hydrocarbon, the five-membered ring has no aromatic properties.
Fluorene is mildly acidic.


When the oxidation of 9-fluorenol (white or colorless) is performed, the major product is 9-fluorenone.
This is an illustration of the pattern of oxidation of a secondary alcohol to a ketone, which usually is not further oxidized.


There is full conjugation of 9-fluorenone that causes it to absorb light of visible frequency.
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.

Will fluorene or fluorenone elute first?

The fluorene is eluted first with the hexane, which makes it easier to elute the 9-fluorenone with the dichloromethane.
The 9-fluorenone will be slower because it is attracted to the alumina.

Why is fluorene nonpolar?

Polarity of Fluorene

Why does fluorene show up under UV light?

Fluorene was visible only under UV light because it is a colorless compound, unlike 9-fluorenone which is yellow.

How many types of hexane are there?
