E2 reaction to take lace on cyclic molecule (cyclohexanes) the X and H must both be axial an a antipt antiperiplanar geometry required
Bent bonds, the antiperiplanar hypothesis and the theory of resonance A accounts for the preferred antiperiplanar geometry of the E2 elimination
E2 occurs via anti-periplanar transition state when possible because If only one proton can be eliminated then geometry of alkene
E2 elimination occurs most often in the anti periplanar geometry The stereochemical requirement of an anti periplanar geometry in an E2 reaction has
A ) E2 reactions involve an antiperiplanar arrangement of a hydrogen atom and the requirement for an anti-periplanar transition state geometry in an E2
