When water (H2O) is added to liquid isopropanol to form a solution, then polar isopropanol molecules are attracted to polar water molecules at the surface of the water. It forms a solution of rubbing alcohol.
<h3>Isopropanol and water in the solution</h3>
Isopropyl alcohol is water-soluble and forms hydrogen bonds with molecules of water (H2O).
When H2O is added to liquid isopropanol to form a solution, H2O spread in a uniform way in the solution.
These isopropanol molecules can surround H2O molecules, which are carried into the solution.
