Witryna12 wrz 2024 · The bond between the carbon atom and the leaving group breaks first. The carbon is left with six bonding electrons, an empty orbital, and a positive charge. In a … WitrynaThe factors that will decide SN1 vs SN2 and whether it is SN1, SN2, E1, E2: 1) Do you have a strong nucleophile? If you do, it will favor an S N 2 reaction in the S N 1 vs S N 2 fight. If it is a mediocre nucleophile, it will favor an S N 1 reaction. This is because of the two mechanisms.

WitrynaFigure 10.8c SN2 reaction. A new carbon portion is introduced in the product with a new carbon-carbon bond formed in the S N 2 reaction, and this is a common method to synthesize internal alkynes with longer carbon chains. A specific example for the synthesis of 2-methyl-3-hexyne from 3-methyl-1-butyne is given here: WitrynaSN1, SN2 can give the same product and E1, E2 may also do so since they are both substitution and elimination reactions. The mechanism depends on the structure of the substrate and the reactant. In this case you need determine if tBuOK is strong or a weak base which will tell you if the reaction is unimolecular (SN1/E1) or bimolecular (SN2/E2).
