A precaution that needs to be taken for working with the nucleophilic medium is ensuring the stability of the carbonation intermediate formed and Steric hindrance.
Discussion:
The likelihood of a nucleophilic substitution reaction proceeding by a dissociative mechanism depends to a large degree on the stability of the carbocation intermediate that forms.
Steric hindrance: Reactions where nucleophiles attack carbon-based electrophiles are significantly more sensitive to steric effects, because empty orbitals on carbon are not as accessible.
