Which of the following statements regarding the E2 mechanism is wrong?...
E2 stands for bimolecular elimination. The reaction involves a one-step mechanism in which carbon-hydrogen and carbon-halogen bonds break to form a double bond (C=C Pi bond).

Which of the following statements regarding the E2 mechanism is wrong?...
Because no intermediate is formed unlike E1 where ionic intermediate ( like carbocation) are formed , just a transtion state is observed so it is a single step rxn

Which of the following statements regarding the E2 mechanism is wrong?...
Explanation:
E2 mechanism is a type of elimination reaction that involves the removal of a proton and a leaving group from adjacent carbon atoms. The term E2 stands for bimolecular elimination as it involves the simultaneous interaction of two molecules or species.
a) Reactions by the E2 mechanism are always bimolecular:
This statement is true. The E2 mechanism involves the interaction of two molecules or species, the substrate and the base, to produce the product. Therefore, the E2 mechanism is always bimolecular.
b) Reactions by the E2 mechanism are generally second order:
This statement is also true. The rate of the E2 reaction is proportional to the concentration of both the substrate and the base. Therefore, the overall order of the reaction is second order.
c) Reactions by the E2 mechanism usually occur in one step:
This statement is true. The E2 mechanism usually occurs in one step where the proton and the leaving group are eliminated from the substrate and the product is formed.
d) Reactions by the E2 mechanism usually occur in two steps:
This statement is wrong. The E2 mechanism usually occurs in one step where the proton and the leaving group are eliminated from the substrate and the product is formed. The E1cb mechanism, on the other hand, occurs in two steps where the leaving group is eliminated first, followed by the removal of a proton.
In conclusion, the correct answer is option 'D' as the statement is false. The E2 mechanism usually occurs in one step and not two steps.
