Course contains basic organic chemistry in very simple manner with illustrations. Fundamental concepts like, Electronegativity, Inductive effect, Resonance effect, Reagents ( Electrophiles, nucleophile, Free radicals), intermediates like carbocation, carbanion, carbene, nitrenes are well described along with detailed organic chemistry with examples. Applications of Inductive effect and resonance effect in deciding strengths of acids, basic stengths of amines, stability of Intermediates like carbocation, carbanion is explained in detailed manner
