Inductive and resonance effects play an important role in understanding a variety of organic chemical reactions and their mechanisms. Most reactions are kinetic-controlled reactions, in which the effects take effect via the stabilization of reactive intermediates over shorter or longer reaction times. - To avoid this mental "detour", we have developed new learning opportunities on equilibrium reactions of organic bases with water for high school teacher education, with which inductive and resonance effects can be quickly worked out using conductivity and pH measurements. The learning opportunity has already been successfully tested in teacher education in Marburg.
