📘 Syllabus

Section A ⚛️

1. Structure and Bonding: Hybridization, bond lengths/angles, bond energy, localized/delocalized bonds, Van der Waals interactions, resonance, hyperconjugation, aromaticity, inductive/field effects, and hydrogen bonding. 🧬
2. Mechanism of Organic Reactions: Curved arrow notation, homolytic/heterolytic bond breaking, electrophiles/nucleophiles, reactive intermediates (carbocations, carbanions, etc.), and methods for determining reaction mechanisms.
3. Alkanes: Isomerism, formation methods (e.g., Wurtz reaction), physical properties, and free radical halogenation mechanisms. 🧪

Section B 🔗

1. Cycloalkanes: Nomenclature, chemical reactions, Baeyer's strain theory, theory of strain-less rings, and banana bonds.
2. Alkenes: Nomenclature, formation methods, Saytzeff rule, Hofmann elimination, and chemical reactions (e.g., hydrogenation, Markownikoff's rule, ozonolysis).
3. Dienes and Alkynes: Classification, chemical reactions (e.g., 1,2- and 1,4-additions), Diels-Alder reaction, acidity, and mechanisms. 🧬
