A complete 20-module journey through CBSE Class 11 & 12 Organic Chemistry — from foundational GOC to biomolecules. Concept-first, mechanism-driven, exam-ready.
Bond fission, reactive intermediates, inductive effect, resonance, hyperconjugation, aromaticity, and acid-base principles — the foundation of everything.
Name any organic compound systematically. Functional group priority, parent chain selection, substituent alphabetization — the language of chemistry.
Structural isomerism, geometric (cis-trans), optical isomerism, chirality, R/S configuration, enantiomers, diastereomers, and meso compounds.
Purification methods (TLC, distillation, crystallisation) and systematic elemental analysis — qualitative Lassaigne's test, quantitative formulae.
CₙH₂ₙ₊₂ — Preparation (Wurtz, Kolbe), free radical halogenation mechanism, selectivity, conformational analysis, combustion, and cracking.
CₙH₂ₙ — Electrophilic addition, Markovnikov's rule, peroxide effect, ozonolysis, Baeyer's test, hydroboration-oxidation, and Zaitsev's rule.
CₙH₂ₙ₋₂ — Triple bond chemistry, acid character of terminal alkynes, hydration, Lindlar vs Birch reduction, silver acetylide test, cyclotrimerisation.
Benzene structure, aromaticity, EAS mechanism, Friedel-Crafts reaction, nitration, sulphonation, directing effects — ortho/para vs meta theory.
Alkyl halides — SN1 vs SN2 mechanism, stereochemistry (Walden inversion), E1 vs E2 elimination, Saytzeff's rule, comparison of leaving groups.
Aryl halides — why less reactive than alkyl halides, nucleophilic aromatic substitution, Meisenheimer complex, and uses of haloarenes.
Alcohols — preparation, physical properties (H-bonding), Lucas test, oxidation, esterification, dehydration, and distinction from phenols.
Phenol's unique acidity, FeCl₃ test, Kolbe-Schmidt reaction, Reimer-Tiemann reaction, Schotten-Baumann, and EAS of phenol ring.
Ethers — Williamson synthesis (SN2), cleavage with HI, physical properties, uses as solvents and anaesthetics, and comparison with alcohols.
Carbonyl group chemistry — nucleophilic addition, Tollens' test, Fehling's test, aldol condensation, Cannizzaro, Clemmensen, Wolf-Kishner reactions.
Carboxylic acids and their derivatives — acidity comparison, nucleophilic acyl substitution, Hell-Volhard-Zelinsky, ester hydrolysis, and acid anhydrides.
Amines as bases — basicity order, Gabriel synthesis, Hoffmann bromamide reaction, Hinsberg test for 1°/2°/3°, and coupling reactions.
Diazonium chemistry — Sandmeyer reaction, Balz-Schiemann, azo coupling to make dyes, and converting −N₂⁺ to various functional groups.
Carbohydrates, proteins, vitamins, nucleic acids — structure, function, and organic chemistry behind the molecules of life.
Addition and condensation polymers, natural vs synthetic, rubber, nylon, Bakelite, PTFE, PVC, and chemistry of medicines, detergents, food.
Identification of functional groups by chemical tests, colour reactions, reagents (Tollens', Fehling's, Baeyer's, FeCl₃, Lucas), and lab safety.
