WebAlkyl halides undergo elimination via two common mechanisms, known as E2 and E1, which show some similarities to S N 2 and S N 1, respectively. In E2, elimination shows a second order rate law, and occurs in a single concerted step (proton abstraction at C α occurring at the same time as C β-X bond cleavage). In E1, elimination goes via a first order rate law, in …

WebApr 22, 2015 · SN1 SN2 E1 Series: Video 4 As an orgo tutor, one of the most common substitution/elimination questions I get relates to “What's the difference between a nucleophile or base?” or “How can I tell a nucleophile from a base?” And the answer? They are THE SAME! Watch this video to understand the concept of Nucleophile vs Base in SN1 … WebNucleophilicity refers to "how much" a reactant wants to "find" a positive charge. In other words, it measures the instability of the reactant's negative charge. Basicity refers to "how much" a reactant wants to "find" a Hydrogen ion. In both of these, the underlying drive is the same--both the base and the nucleophile want to stabilize their ...
