Preparation of p-bromoaniline from p-bromoacetanilide

Answer 1

Take p-bromoacetanilide in a round bottom flask n reflux it on a water bath using ethanol and HCl. Reflux it for around 30 minutes. Cool it in an ice bath and neutralise with 20% NaOH. Filter the separated p-bromoaniline.

Answer 2

When phenol is heated with acetic anhydride crystals of phenyl benzoate are formed which are filtered off washed with water and dried.

There are a number of different ways. Reacting benzoyl chloride with phenol is a good route.

Answer 3

p-Bromoacetanilide can be converted to p-bromoaniline by hydrolyzing the acetamide group using a strong acid like hydrochloric acid or sulfuric acid, which will replace the acetamide group with an amino group. This reaction can be carried out under reflux conditions to ensure complete hydrolysis. After the reaction is complete, the resulting mixture can be extracted with a solvent like ether to isolate the p-bromoaniline.

Answer 4

Synthesis of benzanilide from benzophenone?

Answer 5

C6H5-NH2 + C6H5-Cl-C=O-CH3------------>benzanilide + HCL

Answer 7

Benzoic acid may be prepared by oxidation of benzaldehyde,

C6H5-CHO + KMnO4 = C6H5-COOH

Answer 8

It isn't. Chlorobenzene is prepared by chlorinating benzene.

The resulting compound can be nitrated to produce nitrochlorobenzene, which is then hydrogenated to produce chloroaniline.
