ANSWER:Step 1 of 13
The removal of the proton, the formation of the bond, and the breaking of the bond to the leaving group are the three fundamental steps in an elimination process.
An type of elimination reaction involves the formation of an intermediate and a two-step removal mechanism approach. This kind of reaction is referred to as a "unimolecular reaction." reactions have first-order kinetics.
The nucleophilic elimination reaction that determines the rate of the elimination has two components. Bond-forming and bond-breaking activities happen simultaneously in bimolecular reactions.
