Question

Complete the reaction: C₆H₅NH₂ + H₂SO₄ (conc.)→

Answer 1

This reaction process will be done by the process which is known Sulphonation.

Process :-

When fuming sulphuric acid is heated so in result sulphanilic acid is formed.

_______________________

C₆H₅NH₂ + H₂SO₄ (conc.----)→  NH₂C₆H₅SO₃H ( Sulphanilic acid . )

_______________________

⇒ Here electrophilic aromatic substitution reactions takes place. The temperature is 453-473 K.

⇒ Here Anilium hydrogensulphate is an intermediate product.

The exact reaction is in attachment , you can go through it.

Hope it helps :-)

Answer 2

HEY DEAR ... ✌️

Q.) Complete the reaction: C₆H₅NH₂ + H₂SO₄ (conc.)→

Ans.) The process is Sulphonation .

=) When Aniline is heated reacts with concentrated H2SO4 to form the salt , which on subsequently baking at 455-475K gives sulphanilic acid .

Reaction :-

=) C6H5NH2 + H2SO4 ➡️ C6H5NH5HSO4

455-475K
___________➡️C6H5NH2SOH + ↔️
Baking , H2O

C6H5NH3SO3 .
