WebThis reaction is an E2 reaction (elimination second order), and is promoted by the presence of a strong base. For example, the reaction of t-butyl bromide with hydroxide (or any strong base), shown above. In this case, there is little substitution product, and instead the base simultaneously removes a proton from the β carbon as shown. ... WebAug 27, 2024 · The stereochemistry of E2 reactions depends on the number of β hydrogens. Alkyl halides with two β hydrogens undergo stereoselective elimination to yield the more stable E-alkene as the major product. However, an alkyl halide with only one β hydrogen gives a stereospecific isomer, even if it is the Z-alkene. Table of Contents show.
Rank the alkyl halides in order of increasing E2 reactivity. Then do ...
