Expert Solution
Step 1
E2 -Elimination reaction: The elimination reaction in which the attack of base and elimination of leaving group takes place in a single step is considered as E2-elimination reaction.
E1- Elimination reaction: The elimination reaction which takes place in two steps. The stable carbocation forms in the first step and base abstracts the proton in the second step is considered as E1-reaction.
The first step or the stable carbocation formation step is the slow step and hence it is considered as the rate determining step of the reaction. The second step is the fast step of the reaction.
