Chemical safety information currently selected courses: current semester courses: next semester chemistry instructors. The s n 1 reaction is a two-step reaction in which the leaving group leaves, forming a carbocation this is the slow step, and so the rate is dependent only on the. Learn the specifics of the sn1 reaction : the general form of the s n 1 mechanism is as follows: because the mechanism goes through a carbocation, the leaving group must be attached to.
