WebJan 23, 2024 · In nucleophilic substitution reactions, an electron rich nucleophile bonds with or attacks an electron poor electrophile, resulting in the displacement of a group or atom called the leaving group. Nucleophilic substitution of haloalkanes can be described by two reactions. These two types of reactions are shown in the diagram below. WebThe nucleophile attacks the carbon at 180° to the leaving group, since this provides the best overlap between the nucleophile's lone pair and the C–X σ* antibonding orbital. The …
