The equation for a typical nucleophilic substitution reaction is. Nu⁻ + R-L → Nu-R + L⁻. Nu⁻ is the nucleophile, and R-L is the substrate. The L group is missing from the substrate, so L is the leaving group. Suppose the reaction had been.

"WebThe key difference between the S N 2 and E2 reactions is that the nucleophile in the S N 2 mechanism attacks the carbon connected to the leaving group (ɑ-carbon) while in E2, the base attacks one of the β-hydrogens. The result is a replacement of the leaving group with a nucleophile, in the S N 2, and a newly-formed π bond in the E2 reaction. " - Ots leaving group structure

A leaving group , LG, is an atom (or a group of atoms) that is displaced as stable species taking with it the bonding electrons. Typically the leaving group is an anion ( e.g. Cl -) or a neutral molecule ( e.g. H 2 O). The better the leaving group, the more likely it is to depart. grange hall road beavercreek ohioWebThe rate at which this mechanism occurs is second order kinetics, and depends on both the base and alkyl halide. A good leaving group is required because it is involved in the rate determining step. The leaving groups must be coplanar in order to form a pi bond; carbons go from sp 3 to sp 2 hybridization states. grange hall red bluff ca
