What is a Bromoacetanilide?

What is a Bromoacetanilide?

Description. 4′-Bromoacetanilide is a Pale yellow crystals or powdery crystals. Melting point 168℃, relative density 1.717. Soluble in benzene, chloroform, ethyl acetate, slightly soluble in alcohol, slightly soluble in hot water, insoluble in cold water.

How is para Bromoacetanilide prepared?

PROCEDURE. 10 g of acetanilide is dissolved in 45 ml glacial acetic acid in a 250 ml conical flask and cooled to below 5 degrees. Then 4.2 ml of bromine is added drop wise in to 25 ml cold acetic acid with constant stirring and the bromine solution is transferred to a burette/separating funnel supported over the flask.

What is Bromoacetanilide used for?

4′-Bromoacetanilide is used as an internal standard for phenylurea and the respective metabolic products in oysters. It has also been used as a reagent in the production of a new ligand to form a coordination compex between gadolinium(III) and T=titanium(IV) oxide.

How do you make para bromoaniline?

A preparation method for para-bromoaniline take aniline as raw material, first under zinc powder effect, generates Acetanilide with acetic acid generation acetylization reaction, then generates asepsin with bromine reaction, obtains para-bromoaniline finally by hydrolysis, neutralization reaction.

Why product is major in preparation of p-Bromoacetanilide?

because it is a bulkier group the substitution at the ortho position scarcely occurs, yielding the para mono-substituted compound as the major product (Scheme 5.1. 8.3). This compound, p-bromoacetanilide, already has the substitution pattern of the benzene ring that is desired for the final product.

What is the melting point of 4 Bromoacetanilide?

165-169 °C (lit.)

What is the boiling point of P Bromoacetanilide?

mp. 165-169 °C (lit.)

Which of the following methods can be used to prepare p-bromoaniline as major product?

direct bromination of aniline in presence of Lewis acid.

Why glacial acetic acid is used in preparation of p Bromoacetanilide?

Answer and Explanation: Glacial acetic acid is a polar protic solvent that can dissolve acetanilide.

How do you convert aniline to bromoaniline?

Answer : As aniline is a very activating group, it is first reacted with anhydride to make it less activating , which on reaction with bromine in acetic acid , followed by acid hydrolysis gives p-bromoaniline.
