(a)
Interpretation:
The reaction for the preparation of
Concept introduction:
The replacement of hydrogen atom attached to a carbon atom of electron-rich benzene ring by an electrophile is known as electrophilic
(b)
Interpretation:
The reaction for the preparation of sulfathiazole from aniline is to be stated.
Concept introduction:
The replacement of hydrogen atom attached to a carbon atom of electron-rich benzene ring by an electrophile is known as electrophilic aromatic substitution reaction. The rate of electrophilic aromatic substitution reaction depends on the substituted group on the aromatic ring. The ring deactivating group retards the electrophilic aromatic substitution reaction and ring activating group enhances the electrophilic aromatic substitution reaction.
