" SO3 or electrophile "
Explanation:
The attacking species defines the species that attacks a substrate molecule or intermediate and forms a product is called attacking reagent.
Two types of attacking species:
- Electrophilic reagent it is also called as electrophiles.
- Nucleophilic reagent it is also called as nucleophiles.
The Sulphonation of benzene is carried out by SO3.It is also called as electrophile.This aromatic Sulfonation is used in attacking species.
Most electrophilic substitution reactions are irreversible means they shouldn't involve reverse reaction. But sulphonation is an exception.
So, the Active electrophile (SO3) in sulphonation of benzene is sulphur trioxide.
