WebThe mechanism of the SN2 reaction can be described in more detail by considering its stereo-chemistry. The stereochemistry of a substitution reaction can be investigated only if the car-bon at which substitution occurs is a stereocenter in both … WebThis subclass of nucleophilic substitution occurs when the nucleophile (HS –) attacks the alkene instead of the saturated carbon – the S N 2′ mechanism. This is the due to the saturated carbon being hindered (it is a secondary carbon), making the regular S N 2 mechanism less favourable. Back to more S N 2 reactions
