WebSep 20, 2024 · Leaving group – Better leaving group leads to faster reaction rates. 1 and E1 reactions have exactly the same first step—formation of a carbocation. They differ in what happens to the carbocation. Since in both the reactions, the rate determining steps are the same, they cannot be individually controlled. WebMay 21, 2008 · 0. May 21, 2008. #9. The conjugate base of a strong acid is a good leaving group. For instance, H2O is a great leaving group. We know this because H30+ is a strong acid. The lower the pKa, the better the leaving group. The way I think about it is that a strong acid dissociates completely. mona electric maryland https://bodybeautyspa.org
