Final answer:
Distillation can be used after an E1 reaction to separate and purify the product from the reactants or byproducts.
Step-by-step explanation:
Distillation does not directly help E1 reactions, but it can be used as a method to separate and purify the products of E1 reactions. In an E1 reaction, a carbocation is formed as the rate-determining step, followed by a base capturing the proton and forming the product. Distillation is a technique used to separate liquid components based on their boiling points. After an E1 reaction, distillation can be used to separate the desired product from any remaining reactants or byproducts based on their boiling points. This helps obtain a pure product.
