Ethanol (C2H5OH) and water (H2O) are both liquids at or near room temperature. When a sample of ethanol is poured into a beaker containing water, the two liquids. a. Are miscible because each can hydrogen bond with the other. b. Are immiscible because each has strong hydrogen bonds that cannot be broken. c. Are miscible because both are liquids and all liquids are miscible. d. Are immiscible because organic and non-organic compounds cannot mix.

Troy Leonard · Answer 1

a. Are miscible because each can hydrogen bond with the other.

Explanation:

Both ethanol and water are miscible. The reason why they can both mix freely is due to the hydrogen bonds that will form between their molecular structure.

Hydrogen bonds are special dipole-dipole attraction between polar molecules in which hydrogen atoms are directly joined to an electronegative atom.

Ethanol has an hydroxyl group which will bond to form an intermolecular bond with the oxygen and hydrogen on the water molecule. This attraction makes them miscible.
