### Pericyclic Reactions **Definition:** - A class of organic reactions that proceed via a concerted mechanism involving cyclic transition states. **Types:** 1. **Cycloaddition:** - Two π-systems combine to form a ring. - Example: Diels-Alder reaction, forming a six-membered ring. 2. **Electrocyclic Reactions:** - A conjugated π-system converts to a ring or vice versa. - Example: Ring closure of hexatriene to form cyclohexadiene. 3. **Sigmatropic Rearrangements:**...

### Substitution Reactions **Definition:** - A chemical reaction where an atom or a group of atoms in a molecule is replaced by another atom or group of atoms. **Types:** 1. **Nucleophilic Substitution (S_N1 and S_N2):** - **S_N1 (Unimolecular):** Two-step process, rate depends on the concentration of the substrate. - Example: ( text{R-X} + text{Nu}^- rightarrow text{R-Nu} + text{X}^- ) - **S_N2 (Bimolecular):** One-step process, rate depends on both substrate...

### Benzenoid and Non-Benzenoid Aromatic Compounds **Benzenoid Compounds:** - **Definition:** Aromatic compounds containing at least one benzene ring. - **Structure:** Planar, cyclic, conjugated with alternating double bonds. - **Examples:** Benzene (C₆H₆), naphthalene (C₁₀H₈), anthracene (C₁₄H₁₀). - **Properties:** High stability due to delocalized π-electrons. **Non-Benzenoid Compounds:** - **Definition:** Aromatic compounds not containing a benzene ring. - **Str...
