Question

Tell me the main feature of E2 mechanism???

Answer 1

Answer:

• E2 is a single step elimination, with a single transition state.
• It is typically undergone by primary substituted alkyl halides, but is possible with some secondary alkyl halides and other compounds.
• The reaction rate is second order, because it's influenced by both the alkyl halide and the base (bimolecular).

Answer 2

E2 mechanism

• it is involves one step reaction .
• order of reaction in this case is second .
• poor leaving group is favourable.
• high concentration of a strong base.
• reactive bases favour E2 reaction.
