The missing reagents and structure of the compounds A through I in the given road map are to be elucidated. Concept introduction: Electrophiles are electron deficient species that have positive or partially positive charge. Lewis acids are electrophiles that accept electron pair. Nucleophiles are electron rich species that have negative or partially negative charge. Lewis bases are nucleophiles that donate electron pair. Free radical is an atom, molecule, or ion that has unpaired electrons, which makes it highly chemically reactive. Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a functional group is substituted by any other functional group is called substitution reaction. Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction. Addition reaction: It is the reaction in which unsaturated bonds are converted to saturated molecules by the addition of molecules. The reagent m-CPBA is used for the epoxidation of alkenes . The reagent NBS, in the presence of organic peroxide, is used for allylic bromination. The organic reaction in which dienophile and diene condense to form a cyclic compound is known as Diels-Alder reaction.
