- 9-Aminofluorene has applications in the structural analysis of proteins and carbohydrates. Write a stepwise procedure with equations to show how to separate a mixture of 9-aminofluorene and fluorene in diethyl ether solution.Compound A has the molecular formula C14H25Br and was obtained by thereaction of sodium acetylide with 1,12-dibromododecane. On treatment ofcompound A with sodium amide, compound B (C14H24) was obtained. Ozonolysisof compound B gave the diacid HO2C(CH2)12CO2H. Catalytic hydrogenation ofcompound B over Lindlar palladium gave compound C (C14H26), andhydrogenation over platinum gave compound D (C14H28). Further, C yieldedO=CH(CH2)12CH=O on ozonolysis. Assign structures to compounds A through Dso as to be consistent with the observed transformations.In an aqueous solution containing sodium bicarbonate, aniline reacts quickly withbromine to give 2,4,6-tribromoaniline.

- Assuming you are a chemist and you need to extract ethanolic acid in a benzene solution. Propose and briefly discuss how to extract the ethanolic acid in the benzene solution. Include the reactions involved in each step, if any.Phenols are less acidic than carboxylic acids, with values of pKa around 10. Phenols aredeprotonated by (and therefore soluble in) solutions of sodium hydroxide but not by solutions of sodium bicarbonate.
