Answer 1

Here we've got a strong nucleophile Sulphur and we've got a primary substrate and a polar aprotic solvent. Remember SN2 means subsitution nucelophilc bi molecular. This reaction depends on the strength of the nucleophile and how good your leaving group is. so it happens in one step. Note that you get a back side attack at the carbon with the Cl. Cl we lose that, as our leaving group and we get this product.



Here we've got an SN1 reaction, and a weak nucleophile. If you notice we've got a great leaving group chlorine. chlorine leaves creating a carbocation intermediate and then h2o can come in and attack from either side giving us an alcohol as our product. tertiary alcohol.
