WebSN1 mechanism: Kinetics and substrates. This video talks about the mechanism involved in an SN1 reaction. It also elaborates on what is a rate determining step and how it affects the rate of a reaction. We learn how to calculate the rate of an SN1 reaction and also, what is the order of an SN1 reaction. In the end, it tells why the nucleophile ... WebNow, we've gone over this a little bit with Sn2 and Sn1, but the same idea applies.

WebNo, 2° substrates can react via SN1 or SN2, depending on the conditions. We have two competing processes. If the nucleophile attacks faster than the leaving group spontaneously leaves, the reaction is SN2. If the leaving group leaves before the nucleophile can successfully attack, we have SN1. northern reflections store

In a substitution reaction an existing group on the substrate is removed and a new group takes its place. In an elimination reaction the group is simply removed and no new group comes to take its place and this usually results in a double or triple bond forming in the substrate instead. Hope that helps.
