Solve all problems of NCERT exercise to have command over this portion. Alcohols, Phenols and Ethers and Aldehydes, Ketones and Carboxylic Acids are the two most important chapters from Organic chemistry.
Some important topics from Organic chemistry are- Sandmeyer’s reaction, Nucleophilic substitution reaction, Optical isomerism, Electrophilic substitution reaction, Esterification, Reimer-Tiemann reaction, Kolbe’s reaction, Williamson synthesis, Rosenmud reduction, Gatterman-Koch reaction, Nucleophilic addition reaction, Clemmensen reduction, Wolff-Kishner reduction, Aldol reaction, Haloform reaction, Cross aldol condensation, Cannizzaro reaction, Hell-Volhard Zelinsky reaction, Carbylamine reaction and Coupling reaction.
