Detailed step-by-step reaction mechanisms, carbocation stabilities, and stereochemical inversions for ISC Chemistry board exams.
ISC Chemistry requires explicit arrow-pushing mechanisms illustrating electron movement and transition states.
SN1 proceeds via a two-step carbocation intermediate favoring tertiary halides with racemization. SN2 proceeds via a single concerted transition state with pentavalent carbon, resulting in complete Walden inversion of configuration.
