Organic Chemistry is the branch of chemistry which deals mostly with the objects in life. Though, it is not quite mathematical in nature, but the basics of Thermodynamics and Kinetics are still the underlying principles. It observes and explains the chemistry in life. Although Organic Chemistry in itself is quite vast but at IIT JEE level it deals with General Organic Chemistry. It starts with the concept of Hybridization, IUPAC Nomenclature, Isomerism, Resonance, Hyperconjugation, etc. Stereoisomerism is a critical part which becomes a bottleneck for most of the students. These concepts are used in almost every reaction mechanisms which are a part of topics like Hydrocarbons, Halides, Alcohols & Phenols, Aldehydes & Ketones, Carboxylic acids and derivatives. Named Reactions are like drivers direction for students and maximum come from the chapter of Aldehydes & Ketones, which is no less than a climax of a movie.
Organic chemistry has at least 30-40% weight-age in the IIT JEE chemistry paper. It is the most critical part of chemistry where scoring is important to occupy a high berth in AIR of IIT JEE.
