The skeletal structure of the molecule given is to be drawn. How it can be prepared from a ketone and an amine is also to be shown. Concept introduction: Secondary amines react with aldehydes and ketones to yield enamines, R 2 NCR=CR 2 . The reaction is a typical example of nucleophilic addition reaction in which water is eliminated from the intermediate initially formed leading to the formation of a new C=Nu double bond. To draw: The skeletal structure of the molecule given. To show: How it can be prepared from a ketone and an amine.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

A carboxylic acid has two oxygen atoms, each with two nonbonding pairs of electrons.(a) Draw the resonance forms of a carboxylic acid that is protonated on the hydroxyoxygen atom.(b) Compare the resonance forms with those given previously for an acid protonated on thecarbonyl oxygen atom

Ethyl butyrate, CH3CH2CH2CO2CH2CH3CH3CH2CH2CO2CH2CH3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange and pineapple. Its fragrance and taste are often associated with fresh orange juice, and thus it is most commonly used as orange flavoring. It can be produced by the reaction of butanoic acid with ethanol in the presence of an acid catalyst (H+H+): CH3CH2CH2CO2H(l)+CH2CH3OH(l)H+⟶CH3CH2CH2CO2CH2CH3(l)+H2O(l)CH3CH2CH2CO2H(l)+CH2CH3OH(l)⟶H+CH3CH2CH2CO2CH2CH3(l)+H2O(l) A chemist ran the reaction and obtained 5.40 g of ethyl butyrate. What was the percent yield, The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0% yield. How many grams would be produced from 7.45g of butanoic acid and excess ethanol?
