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. WebHence, structure C is found to be more reactive than A. The reactivity order will be the same for both E1 and E2 as both carry a similar explanation.
