How is P Bromoaniline prepared from aniline?
This is done by acetylation of aniline. The lone pair of ‘N’ in acetanilide is also involved in resonance in the acetyl group. To that extent ring activation decreases. Hence, acetanilide on bromination gives a monobromo product p-bromoacetanilide.

What are the synthetic uses of P Bromoacetanilide?
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 we convert aniline to 4 Bromoaniline Why?
Aniline reacts with Pyridine to give Phenylethanamide (CH3CO)2O. It further reacts with Bromine (Br2) in the presence of acetic acid (CH3COOH) to give Bromoacetanilide (it is the major product in the reaction). It can further react with either Hydogen ion or Hydroxyl ion to give Bromoaniline.
What is the role of glacial acetic acid in the preparation of P-Bromoacetanilide from acetanilide?
This is why glacial acetic acid is used. Bromination of aromatic compounds (like aniline) using Bromine (Br2) takes place by electophilic aromatic substitution mechanism. describe almost pure acetic acid. This is why glacial acetic acid is used.
What is the density of benzocaine?
Benzocaine is sparingly soluble in water; it is more soluble in dilute acids and very soluble in ethanol, chloroform, and ethyl ether. The melting point of benzocaine is 88–90 °C, and the boiling point is about 310 °C. The density of benzocaine is 1.17 g/cm3.
