Can you separate fluorenone from fluorene through recrystallization in an organic chemistry procedure? If so, what...
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.
ORGANIC CHEMISTRY (recrystallization lab) What is the role of the centrifuge and the teflon plug in this experiment? Explain in detail.
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?
I need to write out a procedure for extraction and recrystallization of a 1:1 (by mass) mixture of 1,4-dichlorobenzene/ethyl 4-aminobenzoate. So far, I have that I am starting with extraction using 1 g. of the mixture and dissolving it in about 15mL of diethyl ether. Then I am putting it in a separatory flask and adding 15mL of 1M HCl to get layers. To the organic layer, I will add sodium sulfate and put in rotovap to get a solid....
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.
Write a detailed procedure describing the work up you would use to separate the aniline product from the nitrobenzene starting material. The following solvents/solutions can be used: diethyl ether, water, 10% HCl, and/or 5% NaHCO3.
When isolating fluorenone from your organic layer, you will use a drying agent: A because the ether has seen water and is considered wet. B to get rid of residual benzoic acid. C to get rid of salts. D none of the above.
Ok #Chemistry people,
At this point I’m desperate, because I can follow all the
procedure instructions there is all day, but writing them out is a
No??♀️ I was following the first answer's flowchart and it didn’t
work, I’m pretty sure there are steps missing. Can someone give me
a step by step procedure (not another flowchart), pretty please?
Help a girl out ??? I am Sample B, and its purefication and
extraction and crystallization that we are doing.

Organic Chemistry question. Please show work, so I can learn how to solve the problem. Thanks! What quantity of 7.00 M aqueous H2SO4 (in mL) would be required to neutralize 817 mL of 3.00 M aqueous Ca(OH)2? Please carry maximum number of significant figures through to final answer then round to a whole number.
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
