Fluorenone can be synthesized from fluorene by reaction with NaOH in the presence of oxygen and a catalyst. The first step of the reaction is deprotonation of fluorenone. CH bonds normally have a pK_a in the 50+, but the pK_a of fluorenone is estimated to be 22-23 in dimethylsulfoxide. a) Which hydrogen of fluorenone is deprotonated by NaOH? b) Why is fluorenone so easy to deprotonate compared to a "normal" CH bond. Justify your answer appropriately.

problem set in analytical chemistry spectroscopy : Q. solution of fluorene (diphenylene methane) in benzene can be analyzed by making use of its absorbance at 301 m µ, where C =1.1 x 104 . if a solution of fluorene of unknown concentration in benzene exhibits an absorbance of 0.720 in a 1.00 cm cell. What is the concentration of fluorene?

In what ways can you improve and acid-base extraction procedure for organic chemistry lab? Our napthalene ended up being contaminated with p-nitroaniline, meaning that we didn't get all of the p-nitroaniline in our HCl extract. We're supposed to come up with two ways to improve the technique.

Impure crystalline (solid) substances can be purified by recrystallization from a suitable solvent. Arrange the steps of the recrystallization procedure, from start to finish. Start Weigh the crystals into a tared flask. Dissolve the crude substance in a minimum amount of hot solvent. Filter the hot solution to remove the solid impurities (if present) Allow the solution to cool slowly so crystals form. Filter the crystals. Dry the crystals
