Isopropyl Alcohol

The polar part of alcohol is attracted to and interacts with polar water molecules and causes alcohol to dissolve.

Mineral Oil

The non-polar oil molecule does not interact with water and does not dissolve.

Glucose

The polar parts of the glucose molecule are attracted to and interact with water and cause glucose to dissolve.
