the nucleophile, the more likely the reaction will be SN2 rather than SN1.

examples are acetone, acetonitrile, DMSO, DMF (see below). • anions are not.

How can we tell which mechanism to use? This question will get more complicated unfortunately, but for now we can use the following factors to answer this.

a H+) such as DMF (Dimethylformamide) and DMSO (Dimethyl Sulfoxide).

SN2 Reactions: SN2 reactions proceed well in polar aprotic solvents such as acetone, DMSO, and acetonitrile. Electrophile: a reagent attracted to electrons, they are positively charged or neutral species having vacant orbitals that are attracted to an electron rich centre.

Key Difference – SN1 vs SN2 Reactions The SN1 and SN2 reactions are nucleophilic substitution reactions and most commonly found in Organic Chemistry. The two symbols SN1 and SN2 refer to two reaction mechanisms. The symbol SN stands for “nucleophilic substitution”.

Dimethyl formamide is often used in Sn2 reactions as a solvent. The reason for this is polarity of this solvent. Being an polar solvent it provides a good solvation to the transition state formed in Sn2 reaction.

And for our solvent, we saw in an earlier video, DMSO is a polar A product solvent which favors an S N 2 reaction.

Anti and syn elimination– if it is cyclohexane, it has to be axial (anti) SN1 3>2>1 Forms a carbocation Not effected by strength of nucleophile but a weak nucleophile favors it by not favoring a SN2 reaction Not effected but low concentration disfavors a SN2 reaction Protic polar favors a SN1 reaction if the reactant is not charged.

. Polar aprotic solvents (e.g., THF, DMSO, DMF) are good.

SN2 Reaction: SN2 Reaction is bimolecular or a second order reaction. So, both substrate and nucleophile affect the reaction rate. SN2 Reaction: Polar aprotic such as DMSO and acetone are favorable solvents.

The Quick N’ Dirty Guide To SN1/SN2/E1/E2 Reactions, Part 3: The Role of Solvent. Let’s continue with our Quick N Dirty guide to SN1/SN2/E1/E2 – a quick walkthrough of thinking through this reaction decision. After having examined the substrate and the base/nucleophile in an SN1/SN2/E1/E2 reaction, this post is about the next question to ask:

Protic solvents contain hydrogen bonds, thus O-H or N-H bonds. Examples are water, ethanol (alcohols in general), acids and primary or secondary amines (tertiary amine contains no N-H bond).

The SN2 reaction is a type of reaction mechanism that is common in organic chemistry. In this mechanism, one bond is broken and one bond is formed synchronously, i.e., in one step.
