Steric hindrance at the electrophilic carbon slows the S N 2 reaction.

Steric hindrance at the electrophilic carbon slows the S N 2 reaction. no S N 2. Hammond Postulate : the structure of the transition state for a reaction step is closer to that of the species (reactant or product of the step) to which it is closer in energy. S N 1 reaction transition state
