WebApr 19, 2024 · It is good to know why they are called SN 1 and SN 2; in SN 2 reactions, the rate of the reaction is dependent on two entities (how much nucleophile AND the electrophile is around), and hence it is called SN2. SN 1 reactions' rates are only dependent on on entity, the electrophile (loss of a leaving group is the first step of this reaction and ...

"WebThe preferred solvents for this type of reaction are both polar and protic. The polar nature of the solvent helps to stabilize ionic intermediates whereas the protic nature of the solvent helps solvate the leaving group. Examples of solvents used in S N 1 reactions include water and alcohol. These solvents also act as nucleophiles. " - Solvent effects on sn1 and sn2 reactions
