 The reactivity order is (CH3)3C- > (CH3)2CH- > CH3CH2- > CH3-.Furthermore, studies describe a typical kinetic resolution process that starts out with two enantiomers that are energetically equivalent and, in the end, forms two energy-inequivalent intermediates, referred to as diastereomers.According to Hammond's postulate, the more stable diastereomer is formed faster.
