Atomic Structure and Chemical Bonding Foundations
2-3 weeksReview atomic orbitals, electron configurations, Lewis structures, VSEPR theory, hybridization (sp3, sp2, sp), molecular orbital theory basics, and the nature of sigma and pi bonds. Understand electronegativity, polarity, and intermolecular forces as they apply to organic molecules.

Structure, Nomenclature, and Functional Groups
2-3 weeksLearn IUPAC nomenclature for alkanes, alkenes, alkynes, and cyclic compounds. Master the identification and classification of functional groups: alcohols, ethers, aldehydes, ketones, carboxylic acids, esters, amines, and amides. Practice drawing and interpreting structural, condensed, and skeletal (line-angle) formulas.
Stereochemistry and Conformational Analysis
2-3 weeksStudy conformational analysis of acyclic (Newman projections) and cyclic (chair conformations) molecules. Master stereoisomerism: chirality, R/S configuration, enantiomers, diastereomers, meso compounds, E/Z nomenclature, and optical activity. Understand Fischer projections and how stereochemistry impacts biological activity.
Substitution and Elimination Reactions
3-4 weeksMaster the four fundamental mechanisms: SN1, SN2, E1, and E2. Learn how substrate structure, nucleophile/base strength, solvent, and temperature determine which pathway dominates. Practice predicting products, stereochemistry, and regiochemistry for each mechanism and understand competition between substitution and elimination.
Alkene and Alkyne Reactions
3-4 weeksStudy electrophilic addition reactions of alkenes: hydrohalogenation (Markovnikov and anti-Markovnikov), hydration, halogenation, hydrogenation, hydroboration-oxidation, and epoxidation. Learn alkyne chemistry including terminal alkyne acidity, reduction to cis/trans alkenes, and addition reactions. Understand carbocation rearrangements.
Aromatic Chemistry
2-3 weeksStudy aromaticity, Huckel's rule, and the unique stability of aromatic systems. Master electrophilic aromatic substitution (halogenation, nitration, sulfonation, Friedel-Crafts alkylation/acylation) and understand the directing effects of substituents (ortho/para vs. meta directors, activating vs. deactivating groups). Explore nucleophilic aromatic substitution and benzyne mechanisms.
Carbonyl Chemistry and Carbon-Carbon Bond Formation
4-5 weeksExplore the rich reactivity of carbonyl compounds: nucleophilic addition to aldehydes/ketones, nucleophilic acyl substitution of carboxylic acid derivatives, enolate chemistry (aldol, Claisen, Michael, and Wittig reactions), Grignard and organolithium reactions. Understand amide bond formation, oxidation-reduction sequences, and the reactivity hierarchy of carboxylic acid derivatives.
Spectroscopy, Synthesis Design, and Advanced Topics
4-5 weeksLearn to determine molecular structure using IR, 1H-NMR, 13C-NMR, and mass spectrometry. Practice retrosynthetic analysis and multi-step synthesis design. Explore advanced topics including pericyclic reactions (Diels-Alder, sigmatropic rearrangements), radical reactions, organometallic catalysis, green chemistry principles, and connections to biochemistry (amino acids, carbohydrates, lipids, nucleic acids).
