EXCEPTION CASES
1. Allyl halides:
ALTHOUGH being primary alkyl halides, they can react
by SN1 mechanism (weak nucleophile) due to
stabilization of the formed carbocation by resonance
and minimum steric effect.
Due to symmetry, one
product is formed
+
2. Benzyl halides:
ALTHOUGH being primary alkyl halides, they can
react by SN1 mechanism (weak nucleophile) due to
stabilization of the formed carbocation by
resonance.
