In 1962, george a. olah directly observed the formation of a carbocation intermediate using a technique called nuclear magnetic resonance (nmr) spectroscopy. typically, carbocation intermediates are short-lived and very reactive, which makes them difficult to observe in order to determine that a mechanism proceeds through a carbocation intermediate. in the examples below, indicate all the organic intermediates that would form from the given reactants and specified reaction mechanism, and identify if these intermediates are reactive or not reactive
