... Stability/Reactivity/Selectivity Principles 1. Reactant Stability/Reactivity: The more stable the reactant, the less reactive it will be. In terms of rates, this means that the more stable the reactant, the slower it will react. (The concept here is that the more stable the reactant, the more conten ...
