Why is ethanol soluble in water

1 answer

Ethanol is soluble in water because of their similar molecular structures. Ethanol is a small polar molecule with a hydroxyl group (OH) that is capable of forming hydrogen bonds with water molecules. This allows ethanol to mix well with water and dissolve in it. Additionally, ethanol molecules have a partial positive charge on the carbon atom and a partial negative charge on the oxygen atom, making it capable of forming hydrogen bonds with water molecules. As a result, ethanol is miscible in water, meaning it can mix in any proportion with water.
