Answer:
hydrogen bonding
Step-by-step explanation:
A waxy surface is nonpolar whereas water is polar. There is an electronegativity difference between the O and H atoms, where O is more electrongative than H. This electronegativity difference cause the two O-H covalent bonds in water to become polar, where the O atom has a partial negative charge and the H atom has a partial positive charge. The polar O-H bond causes intermolecular bonding in water molecules through hydrogen bonding. This causes water to form small drops on a waxy surface.
