Organic Chemistry Unknown Identification: Day I

Today...well yesterday I suppose...the identification of an unknown solid began.
Unknown No. 19.
A bright yellow solid.
It would not dissolve in H2O, NaOH, NaHCO3, H2SO4, or HCl.

Aromatic Hydrocarbon?
Aliphatic Hydrocarbon?
Diaryl Ether?
Perfluoror Alcohol?
Ester?
Ketone?

It dissolved in acetone which helped greatly with cleaning the glassware. And quite well in CDCl3 for the NMR spectroscopy solutions.
Run through NMR hydrogen and carbon spectroscopy. (Figure(s) ?)
Melting point determined. 80-84 degrees Celsius. Closer to 84 degrees.

More details to come soon (I just need to look at my notes in my lab book and examine the NMRs).
