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

Synthesis of benzanilide from benzophenone?

Answer 4

Answer 6

Benzoic acid may be prepared by oxidation of benzaldehyde,

C6H5-CHO + KMnO4 = C6H5-COOH

Answer 7

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.
