WebApr 28, 2010 · Key concepts to understand: 1) Leaving group ability (related to pKa) – the better the leaving group, the more reactive it will be in an SN2 . 2) Steric hindrance (primary alkyl halides are more reactive than secondary). 3) Stereochemistry – SN2 occurs with inversion. Examples: Enolate alkylation royal surrey snookerWebSince the pKa value of terminal alkynes is about 25, they do require a very strong base to deprotonate them. A typical example of such a base is sodium amide NaNH 2.
