FAQs on PYQs: Aromatic & Heterocyclic Reactions Video Lecture - Organic Chemistry

1. What are some common reactions involving aromatic compounds?
Ans. Common reactions involving aromatic compounds include electrophilic aromatic substitution, nucleophilic aromatic substitution, and oxidation reactions. These reactions allow for the introduction of various functional groups onto the aromatic ring.
2. How are heterocyclic compounds different from aromatic compounds?
Ans. Heterocyclic compounds contain at least one heteroatom (an atom other than carbon) within the ring structure, whereas aromatic compounds only contain carbon atoms in their ring structure. This heteroatom can be elements such as nitrogen, oxygen, or sulfur.
3. What is electrophilic aromatic substitution?
Ans. Electrophilic aromatic substitution is a reaction where an electrophile replaces a hydrogen atom on an aromatic ring. This reaction is characterized by the attack of the electrophile on the electron-rich aromatic ring, followed by the elimination of a proton to restore aromaticity.
4. What is nucleophilic aromatic substitution?
Ans. Nucleophilic aromatic substitution is a reaction where a nucleophile replaces a leaving group on an aromatic ring. This reaction involves the attack of the nucleophile on the electrophilic carbon atom attached to the aromatic ring, followed by the elimination of the leaving group.
5. How can aromatic compounds be oxidized?
Ans. Aromatic compounds can be oxidized using various oxidizing agents such as potassium permanganate (KMnO4) or chromic acid (H2CrO4). These oxidations typically involve the conversion of a benzene ring to a benzoic acid or the introduction of other functional groups onto the aromatic ring.
