Functional group present in 9-fluorenone (6) other than the
Concept Introduction :
Column chromatography is a large scale solid-liquid adsorption chromatographic technique that can separate multi-gram amounts of mixtures. This is a preparative version of thin layer chromatography that permits separation and isolation of products by a collection of eluted fractions.
(b)
Interpretation:
More polar compounds from fluorine and 9-fluorenone should be identified and explained.

- Sketch a flow injection apparatus for the determination of sodium sulfite in aqueous samples.arrow_forwardA TLC plate showed two spots with Rf values of 0.25 and 0.26. The plate was removed from the developing chamber, the residual solvent was allowed to evaporate from the plate, and then the plate was returned to the developing chamber. What would you expect to see after the second development was complete?arrow_forwardAfter extracting NaOH two times from ether, does the amount of precipitate after adding HCl in both tubes indicate that all acid impurity has been removed from the ether layer containing the neutral compound? There was a lot of precipitate in the first extraction and almost nothing in the second extraction after adding HCl to both.arrow_forward
- In addition to a low boiling point and immiscibility with water, why is density important to consider in the selection of an extraction solvent? Would an organic liquid with a density of 1.006 g/mL make a good extraction solvent? Explain.Write the chemical reaction that took place during this experiment.arrow_forward1. Why is the washing of crystals on the filter paper not as effective a process of purification as crystallization?2. How do you account for the formation of crystals of different sizes in slow and rapid crystallization process?3. What properties should ideally be possessed by a recrystallization solvent?arrow_forwardThe purpose of this experiment is to use both extraction and crystallization techniques to separate a solid mixture of organic compounds. You will receive a packet with 1 g of a unknown (pH is basic) amide solid sample which will contain three components, one from each group: Group 1 (~50% wt): ethyl 4-aminobenzoate, ortho-toluic acid, or benzoic acid Group 2 (~40% wt): fluorene, 1,4-dibromobenzene, benzil, benzoin Group 3 (~10% wt): fluorene, 1,4-dibromobenzene, benzil, benzoin (but not the same as Group 2 compound) Create a lab procedure that will allow you to successfully isolate, purify, and identify the two major (Group 1 and Group 2) components of the unknown amide sample. reagents that can be used are 1M HCl, 6M HCl, 1M NaOH, 6M NaOH, diethyl ether, and methylene chloridearrow_forward
