The
An E2 reaction is a concerted, one-step reaction in which the proton and the halide ion are removed in the same step.
For
A good nucleophile/strong base favors
In primary alkyl halides substitution take place.
In secondary alkyl halides substitution and elimination take place (strong. bulky bases and high temperatures favor elimination over substitution).
In tertiary alkyl halides only elimination takes place
