WebFigure 1. a. The SN2 reaction of an iodide anion with 2-bromobutane. b. The SN1 reaction of a hydroxide anion with 2-bromo-2-methylpropane. Note that the SN2 reaction occurs in one step, while the SN1 reaction occurs in two. Various factors can influence the rates of substitution reactions as well as whether or not the reaction will be SN1 or SN2.

What is the explanation that best describes this transformation? an SN1 reaction has occurred due to carbocation formation Which nucleophilic substitution reaction is not likely to occur? I- + CH3CH2-OH → CH3CH2-I + OH- In chemistry, a nucleophilic substitution is a class of chemical reactions in which an electron-rich chemical species (known as a nucleophile) replaces a functional group within another electron-deficient molecule (known as the electrophile). The molecule that contains the electrophile and the leaving functional group is called the substrate. The most general form of the reaction may be given as the following: how are bitmap and vector images stored
