Concept introduction:
Elimination reaction:
An elimination reaction is removal of two substituents in a molecule and forms alkene. An elimination reaction is one or two-step process which based on the mechanism when two substituents removed from the molecule in single step is called E2 reaction. When two substituents are removed from the molecule in two steps is called E1 reaction.
E1 elimination:
Saytzeff's Rule:
It is elimination reaction in which the formation of olefin on most hindered or highly substituted position.

The E1 and E2 elimination reactions of this substrate lead to two different alkene isomer products (E or Z). Propose a mechanism for the E1 and E2 reactions and predict which isomer is the major product of each. Explain why each mechanism yields a different product. H3C, H H Br H₂O E1 VS. NaOH E2 E CH3 or Z CH3arrow_forwardTreatment of propadiene (an allene) with hydrogen bromide produces 2-bromopropene as the major product. This suggests that the more stable carbocation intermediate is produced by the addition of a proton to Br HBr. H2C=C=CH, H3C CH2 a terminal carbon rather than to the central carbon. Propadiene 2-Bromopropene (a) Draw both carbocation intermediates that can be produced by the addition of a proton to the allene. (b) Explain the relative stabilities of those intermediates. Hint: Draw the orbital picture of the intermediates and consider whether the CH, groups in propadiene are in the same plane.arrow_forward
