(iv). Lewis Bases

What type of reagents effect characteristic benzene substitution? Why is it called, electrophilic aromatic substitution?

Nucleophiles act as Lewis bases and electrophiles act as Lewis acids

What are Lewis acids and bases?

All electrophilies are Lewis acids while nucleophiles are Lewis bases. Justify.
