explain the mechanism of nitrogen of benzene
Answers
Answer:
Benzene is highly prone to electrophilic substitution reactions compared to addition reactions as it loses its aromaticity during addition reaction. As benzene contains delocalized electrons spanning over carbon atoms in the ring, it is highly attractive to electrophiles and is also highly stable to electrophilic substitutions. Generally, the electrophilic substitution reaction of benzene is a three-step process involving:
Generation of the electrophile.
Intermediate carbocation formation.
Removal of proton from carbocation intermediate.
Common benzene reactions are
Nitration of Benzene
Benzene reacts with concentrated nitric acid at 323-333k in the presence of concentrated sulphuric acid to form nitrobenzene. This reaction is known as nitration of benzene.
