Slight attractions that develop between oppositely charged regions of nearby molecules.
When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Chemists call such intermolecular forces of attraction van der Waals forces. (This also occurs in the phenomenon known as Hydrogen-bonding.) What is the alternate of a slight attraction - it is called the covalent bond. Note that an ionic bond is a type of covalent bond.
Molecules that do not have oppositely charged ends are nonpolar molecules.

Hydrogen bond
Molecules that do not have oppositely charged ends are nonpolar molecules.
Ionic bonds
Ionic substances are held together ionic bonds, which are the electrostatic attractions between oppositely charged ions.
Nonpolar molecule is one which electrons are shared equally in bonds. Such a molecule does not have oppositely charged ends. This is true of molecules made from two identical atoms or molecules that are symmetric, such as CCl4.
When polar molecules are placed between oppositely charged metal plates they will align themselves. They align in the direction of the field.
Those molecules are polar.
The strong ionic forces (electrostatic) of attractions that exists between the positively and negatively charged molecules keeps the ions together. remember that oppositely charged ions tend to attract. The is also weak Van der waals forces of attraction.
