The nucleophilic substitution reaction of second order (S N 2) at a silicon atom is scrutinized using snapshots along a pseudo‐reaction coordinate, starting with an experimentally isolated phosphino‐fluorosilane as a model for the ion‐molecule complex and the corresponding silylphosphonium cation as a model of the product. It is crucial to combine different bonding descriptors from real and orbital space to understand the pseudo‐reaction; they reveal different aspects based on the different sensitivity to dispersive, electrostatic and polar‐covalent contributions to bonding.
