N代表nucleophilic（亲核的），数字1和2就代表反应级数（order of reaction）。

SN1reaction follows first-order kinetics, that is, the rate of reaction depends on the concentration of only one reactant, which is tert-butyl bromide and is independent of the concentration of hydroxide ion. Rate $=k\left[\left(\mathrm{CH}_{3}\right)_{3} \mathrm{CBr}\right]$. Hence...
The SN1 reaction occurs in two distinct steps, beginning with the formation of a carbocation intermediate, while the SN2 reaction is a single, concerted step where the nucleophile attacks the substrate simultaneously as the leaving group departs. This article delves into these two types of nucleophi...

The meaning of SN1 reaction lies in the name itself “substitution, nucleophilic, and unimolecular.” Therefore, this reaction will follow the first order kinetics. In another term, we can say that the rate determining step in this reaction is unimolecular. Moreover, the rate of reaction w...
