SN1 substitution proceeds through the formation of a carbocation intermediate and the preference for this mechanism depends on the stability of the carbocation formed.
The order of preference is as follows: benzyl > allyl > tertiary > primary > secondary > primary > alkyl halides.
Moreover, SN1 reaction is favoured over SN2 by heavy groups on the carbon atom attached to halogen due to steric hindrance.
Since benzyl carbocation is resonance stabilised, nucleophilic substitution of Benzyl chloride invariably proceeds through SN1.
