This book ''Organic Chemistry for Competitions" make easy the Reaction Mechanism, Resonance, Acid-Base concepts, Electronic effects, Steric effects and shows how acidity and basicity are altered by these effects. Several examples has been described which are very useful for students preparing for JEE (IIT Entrance), AIEEE and other Engineering competitive entrance examination tests. At the end two sets of hundred specimen questions as Screening Test I & II are given which are very useful for the entrance tests. Key Features: Basic Concept of Electron Displacement Inductive Effect Steric Hinderance Effect Reactivity of Alkyl Halides Dienes Reaction Mechanism Organic Reagents Fission of Bonds Free Radicals Carbanions Expected Problems Kharasch Effect or Peroxide Effect Screening Test Free Radicals JEE (IIT), AIEEE, Papers
