What could be a potential use of adipic acid? A) Not much, adipic acid is a 1,6-dicarboxylic acid, so it easily decarboxylates. B) Adipic acid is extensively used in turophilic chemistry. C) Adipic acid is structurally related to sebacic acid. - We used sabacic acid to make 6,1d-Nylon. So if adipic acid were converted into its acid chloride, and then reacted with hexane-1,6-diamine, one could make 6,6-Nylon. D) Adipic acid is extremely toxic, so it is seldomly used in synthetic chemistry.
Why is it that benzenesulfonamides of primary amines are more soluble in aqueous alkali than the corresponding benzamides?
A mixture of compounds is dissolved in ether, and extracted with 10% NaHCO3 solution. The aqueous extract is treated with 6M HCI solution, and extracted with dichloromethane. If the mixture contains an amine, where is it? The bottom layer of the first extraction O The top layer of the second extraction The top layer of the first extraction The bottom layer of the second extraction
Provide the correct structure from the IUPAC name. (a) 2-aminocyclopropanecarboxylic acid (b) 3-mercapto-5-oxoheptanal (c) Propyl 2,2,4-trimethyloct-4-enoate (d) 4-oxocycloheptanecarbaldehyde (e) N,N,4,4-tetraethylhexanamide (f) Acetic pentanoic anhydride (g) Acetyl chloride (h) Methyl 3,3-diethyl-6-octynoate
Why did you use potassium tert-butoxide as the base, as opposed to the “usual” Wittig base nbutyllithium? a) n-butyllithium is nucleophilic, and would react with the ester group in the reactant b) n-butyllithium is pyrophoric and needs to be handled under inert atmosphere.c) The phosphonium salt is “activated”, and only requires a relatively weak base to form the ylide.d) none of the above.e) all of the above
Write chemical equations expressing each of the following: (a) Preparation of o-nitrophenyl acetate by sulfuric acid catalysis of the reaction between a phenol and an acid anhydride. (b) Esterification of 2-naphthol with acetic anhydride in aqueous sodium hydroxide (c) Reaction of phenol with benzoyl chloride

In the preparation of p-Nitroaniline, there are three synthetic steps in this reaction, the first is acetylation of the amine, second is nitrates and the third is hydrolysis of the amide. Why must acetylation be done first if at all? Use chemical structures to illustrate your point.

What is the critical extent of reaction (pc) based on Carother's approach to gelation for the synthesis of a polyamide using equimolar amounts of diethylene triamine and the acid chloride of trimesic acid (see structures below; assume only the primary amines react). Some helpful equations: Carothers Equation: p. = 2/fav, where fav = (ENfi) /ENi CI H2N `NH2
