The compound (S)-(+)-2-Butanol is a chiral molecule that is used in the synthesis of benzodiazepines. The (+) enantiomer of 2-butanol has been shown to bind to the GABA receptor and has an inhibitory effect on benzodiazepine binding. It is also a competitive inhibitor for the enzyme dehydrogenase, which converts 2-butanol to acetaldehyde. The (-) enantiomer of 2-butanol does not have any effect on the GABA receptor or dehydrogenase activity. This means that the (+) enantiomer is responsible for the activation energy and stereoselectivity of this reaction. The activation energy for this reaction can be calculated by measuring the amount of heat released during the reaction. This process can be done through vibrational spectroscopy or by running control experiments with a known concentration of reactants and products. There are many ways to determine whether this reaction follows an elimination or dehydration mechanism,
