Ice water used to cool the distillate in the E1 experiment because the distillate is volatile in nature and present in vapour form.
Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation.
Unsaturated compounds are produced during elimination processes. An alkene is created during the removal of alcohol. Alkyl halides also go through elimination processes. We will do an acid-catalyzed elimination using a secondary alcohol that is second order (E1), meaning that the rate of reaction depends on how quickly the intermediate carbocation may be produced.
Ice water helps in condensing or cooling down the vapours coming to the condensing tube (i.e. distillate).
Because the resulting alkene has a low boiling point, the receiver flask is put in an ice water bath to keep it cool throughout the reaction and distillation.
Hence, Ice water used to cool the distillate in the E1 experiment because the distillate is volatile in nature and present in vapour form.
