0不+ Reactions 花院 Bond formation Basically,most reactions involve electron- rich molecules forming bonds to electron deficient molecules (i.e.nucleophiles forming bonds to electrophiles). The bond will be formed specifically between the nucleophilic center of the nucleophile and the electrophilic center of the electrophile
