Being unstable carbocation is not formed in sn2 and direct product is formed.But as carbocation is stable in sn1 intermediate step is shown.

SN2 reactions proceed via a concerted mechanism, meaning that there is just one step. The nucleophile attacks the carbon attached to the leaving group, from the other side as the leaving group, and the C-LG bond cleaves simultaneously.
