Where am I going wrong. Not giving equivalents, temperatures, solvents, reaction times etc.

Home Synthesis of p-bromoacetanilide from acetanilide. Used as analgesic and antipyretic. Synthesis of benzil from benzoin Organic Chemistry Here alcohol group of benzoin is oxidized to ketone group forming benzil in the presence of concentrated nitric acid Bromination of acetanilide Ask Question.

This prevents the formation of polybrominated site products. But because the oxidation is relatively slow, low concentration of Br2 is formed at a time.

Synthesis of p-bromoacetanilide from acetanilide

Post as a guest Name. Also, I find the description given in http: However, I still find it amazing that there is exclusively no byproduct formed.

If the colour of the solution is persistently yellow, about g of sodium bisulphite is added with constant stirring to bleach coloration. If you would have used more equivalents, chances are acstanilide you would have gotten d as well. Zhe I uploaded the source.


Tatchell; Fifth Edition; Page No. X g of p-bromo acetanilide.

Synthesis of p-bromoacetanilide from acetanilide – Labmonk

Home Questions Tags Users Unanswered. Hydrolysis of Ethyl Acetate Organic Brpmination Complete hydrolysis can be rapidly obtained, if the ester is boiled under reflux with a dilute aqueous solution of Glacial acetic acid 70 ml. Thus, it is very likely that we can selectively stop the reaction after monobromination. Contents of the flask are poured directly into a beaker having ml ice cold water. Log in with Facebook. Bromination of acetanilide gives para brominated acetanilide mainly, because amino group of acetanilide is protected by acetyl group.

It probably does give some of the ortho product. Synthesis of 2, 4, 6-tribromoaniline from aniline Organic Chemistry Acetanilice undergoes nucleophilic substitution with bromine, even in cold.

The truth though is that most people only care about such things broination they actually have to go into the lab and do it.

Therefore, 10 g of acetanilide would give…………………. Here one mole of methyl salicylate oil of Complete hydrolysis can be bgomination obtained, if the ester is boiled under reflux with a dilute aqueous solution of I am inserting the question and solution screenshots for reference. Sodium bisulphite sufficient quantity.

reaction mechanism – Bromination of acetanilide – Chemistry Stack Exchange

Turning the amino group into an amide serves two purposes: Mono substituted products of primary amine cannot prepared easily by direct action of a reagent. The question still arises why we only obtain the para -product. Alkaline hydrolysis of esters is called saponification and is an irreversible process. That should block one of the two ortho positions sterically.

We expect the amide bond to be as complanar as possible with respect to the benzene ring to maximise electronic interactions. The conical flask is further rinsed with 50 ml cold water and transferred into the beaker with stirring. Synthesis of Dibenzal Acetone from Benzaldehyde by Claison Schmidt Reaction Organic Chemistry When an ethanolic solution containing acetone and its two equivalents of benzaldehyde is made alkaline with sodium hydroxide, rapid
