Abstract A unified description of chemical reactivity is made possible with valence bond (VB) diagrams, such as those shown for the a simple case (only reactants and products must be considered) and a more complex system (an intermediate state also plays an important role; RC = reaction coordinate). Analysis of reactivity and mechanistic problems in organic and organometallic chemistry exemplifies the generality of the VB paradigm: in situ DNA repair, C−F and C−H bond activation, S RN 2 c mechanism, stepwise versus concerted cycloaddition, and a lot more.
