"WebSN2 - Sodium nitrate must displace the leaving group if it is to act as a nucleophile in sn2. When this occurs, nucleophiles have a charge. If not, there must be a strong neutral nucleophile present. Despite this, one should also consider steric factors, as a bulky nucleophile can prevent the SN2 reaction from taking place.

Comparing SN2 reaction rates - Chemistry Stack Exchange

WebAug 11, 2015 · With SN 2 reactions, a replacement occurs via backside attack, a spatial pathway that is fairly simple to figure out if the nucleophile is fairly strong (i.e. it has a strong desire to forgo its "laziness" and try harder) and has low steric hindrance (is not bulky). WebA molecule’s steric hindrance can be used to favor a specific reaction. For example, there are two types of substitution reactions, Sn1 and Sn2. Both of these reactions can be performed with simple molecules; however, Sn1 can occur with bulky molecules, while Sn2 cannot because it is too congested for the mechanism known as a ‘backside attack’.

WebSteric Hindrance: non-bonding interactions between molecules, resulting from their physical shape, that affect the ways in which they interact. 1. SN1 vs. SN2 Rate Equations The numbers associated with SN1 and SN2 reactions can seem counterintuitive at first. If you think about the number of steps involved in these reactions, they seem backwards. WebSince the substrate is involved in the RLS, if the steric hindrance of the substrate around the leaving group increases, the rate if the reaction decreases Why does the nucleophile prefer to attack carbon in SN2? The nucleophile would perfer to attack carbon because it is partially positley charged.
