    Ethanol is an alchohol

    Alcohols have an hydroxy(OH) group this group allows the formation of hydrogen bonds with water.

    This allows ethanol and water to be miscible.

    I know there are a lot of questions that can't be answered by Googling, but this isn't one of them.

    First response poster has this, but essentially if a Hydrogen is bonded to a strongly electronegative atom (Nitrogen, Fluorine or Oxygen) it can form hydrogen bonds, since both water and alcohols have an OH they can hydrogen bond with each other, this makes them miscible
