Web17 Aug 2014 · SN2, as its name suggests, is a bimolecular mechanism and its rate depends on not just substrate concentration but also nucleophile concentration. SN1, however, is solely dependent on substrate concentration, as carbocation formation has a high activation energy barrier, and overcoming this barrier takes time. I proposed to repeat the experiment. Web•Bromobutane can potentially undergo substitution or elimination reactions with acetic acid depending on the reaction conditions. • If the reaction is carried out in the presence of a strong nucleophile, such as hydroxide ion, the primary reaction mechanism will be SN2 (substitution nucleophilic bimolecular), in which the nucleophile attacks the carbon … duke urologic assembly
