Nitration of Acetanilide Introduction When organic compounds are nitrated it changes the composition and reaction of the compounds.[4] We could benefit from these changes‚ nitration of acetanilide produces a product called p- Nirtoanoline. P-Nitroaniline is commonly used as an intermediate in the synthesis of dyes‚ antioxidants‚ pharmaceuticals and gasoline. P-Nitroaniline is also used in gum inhibitors‚ poultry medicines and as a corrosion inhibitor. [2] Nitration is a type of chemical

major types. Hydrocarbons react differently in reagents. The basis of determining an unknown hydrocarbon is due to the differences in reactions of hydrocarbons. An unknown compound is determined using tests. The unknown gives a positive result in nitration test and gives no brown precipitate in oxidation test. The unknown is an aromatic and non-alkylated compound. _______________________________________________ Introduction: Hydrocarbons are organic compounds that composed of only hydrogen and

Abstract: The purpose of this lab is to prepare phenylmagnesium bromide‚ a Grignard reagent‚ and react it with benzophenone to give triphenylmethanol. Once made‚ the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone‚ benzophenone. The result is an alkoxide that is then protonated to give the alcohol‚ triphenylmethanol. The purity of the final product will then be considered by melting point and IR spectroscopy. Final purified triphenylmethanol weighed 8.02 grams

Abstract This experiment is about the synthesis of 3-nitrobenzaldehyde through nitration. The nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction‚ in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a suitable electrophilic reagent‚ and many other groups besides nitro may be introduced into the ring. Although the reaction produced a low

Department of Psychology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Four organic samples: hexane‚ cyclohexene‚ napthalene and toulene were given to serve as reference standards to characterize and distinguish four unknown given samples. Nitration‚ bromine and basic oxidation testswere conducted to classify the different samples from being an aliphatic‚ or aromatic‚ saturated or unsaturated and alkylated or non-alkylated hydrocarbons. The physical state and color were noted by simple physical

as well as an iodine crystal‚ which facilitates the reaction by cleaning the surface of the magnesium metal. Bromobenzene and anhydrous diethyl ether were then added to the flask. Anhydrous ether was used because at this point‚ no water was to enter the reaction. The reaction was triggered by swirling and the heat of a human hand. From here‚ the refluxing began and ended once the bromobenzene addition was completed. The second phase of the experiment involved the reaction of the phenylmagnesium bromide

electrophile in the nitration reaction‚ will attack the benzene ring and produces the nitrobenzene ring. Resonance-stabilized arenium ion is created when the nucleophilic carbon pi bond on the acetanilide reacts with the nitronium ion. The aromaticity of the compound is lost in this important step. Water‚ acting as the Lewis base‚ removes a proton from the carbon bonded to the nitro group‚ an aromatic benzyl structure is created again: nitroacetanilide; thus ending the nitration reaction (1).
