9-fluorenone is different because it is a ketone with all of its carbons tied up in double bonds. There are no readily available acidic hydrogens, therefore this makes the pka of the molecule much greater than most other ketones.

What is the pKa of 9-Fluorenone?
9-Fluoreneone is different from many ketones as it does not have any acidic protons alpha to the ketone. The only protons available are attached to the aromatic rings, so the pKa would be fairly similar to, perhaps slightly lower than, the pKa of benzene, 43.
Why does a hydrophobic environment increase the pKa of Histidine?
The pKa, or acid dissociation constant, of an amino acid is strongly tied to the properties of the surrounding solvent. The hydrophobic core of a protein is a distinctly different environment than the water exposed surface of the protein and the pKa in the core is different than the normal, solvent exposed pKa. This is related to the dielectric constant, or the ease at which charge is "felt" over a distance, which is much lower in the hydrophobic core of the protein. In addition, the now fixed locations of other possibly charged amino acids nearby will also impact the pKa of the residue.

Where can you find a list of pKa or acid values for different types of oil?
Er... Oil doesn't normally have a pKa, as oil isn't an acid. It's non-polar.
What is the pka of bromoacetic acid?
pKa=2.86
What is PKa value of benzyl alcohol?
pKa = 15
PKa value of diethylmalonate?
It is around pKa=13
What is the pka value of Doxofylline?
Doxofylline Pka value is about 9.8.
Does pka changes with temperature?
pKa (dissociation constant) is variable with temperature.
What is the pka value of ether?
The pka of a protonated ether (the conjugate acid) is about -3.5
