In regards to the synthesis of 9-fluorenone via sodium
hypochlorite oxidation of 9-fluorenol (9-Fluorenol ->
9-fluorenone) lab answer the following question:
What would happen if this oxidation were carried out with
9-methyl-9-fluorenol?
Can you please explain the oxidation reaction of 9-fluorenol to
9-fluorenone using sodium hypochlorite, preferably a detailed
explanation of everything that is happening.
A sample of 9-fluorenone is contaminated with an impurity that
is insoluble in ethanol. 9-Fluorenone is a bright yellow solid that
dissolves in hot ethanol. Use this information to design the
experimental procedure to purify 9-fluorenone. Describe the
procedure.
1.1g of 9-fluorenol mixed with 11.1mL of hot methanol .11g of
NaBH4 was then added. 3M of sulfuric acid was then added to the
mixture, resulting in the formation of a solid. The mixture was
then heated until the solid that formed upon the acid addition was
dissolved in the solvent(methanol), and then cooled to room
temperature.
9-fluorenol NMR: I've provided two sets of NMR's. The
theoretical vs. the experimental. In the theoretical I understand
all the shifts except for...
What is the mechanism for separating 9-fluorenone and a
carboxylic acid in mixture? We are using a separatory funnel and
adding the mixture of 9-fluorenone and a carboxylic acid to it. I
need to know the mechanism of how they will separate into an
aqueous and an organic layer.
9-fluorenol NMR: I've provided two sets of NMR's. The
theoretical vs. the experimental. In the theoretical I understand
all the shifts except for the 2.06, representative of the H alpha
to the OH group. Methine protons usually have a shift around 1.7ppm
and protons alpha to an (OH) are deshieled adding +2.5ppm,
according to my textbook, which would make me think that the actual
shift be 4.2ppm. Why is this not the case? Could I be mistaking
this nuclei for...
1. How would the reaction be affected if bromoethane were used
instead of iodoethane?
2. How would the reaction be affected if 2-iodopropane were used
instead of iodoethane?
