# Do E1 reactions require a strong base, like E2 reactions?

No. The base is not involved in the rate determining step, so the nature of the base is unimportant in an $\text{E} 1$ reaction.
But, the stronger the base, the more likely an $\text{E} 2$ reaction becomes.
$\text{E} 2$ reactions always involve a strong base. They need chemicals strong enough to pull off a weakly acidic hydrogen atom. These are usually charged bases like C₂H₅O⁻ and (CH₃)₃CO⁻.
If the strongest base in your reaction mixture is an uncharged molecule, you will get an $\text{E} 1$ reaction.
