Water is known as the universal solvent. one reason water makes a good solvent is because it is composed of polar molecules. what makes a water molecule a polar molecule? a. the water molecule never develops a charge and is always neutral. water molecules are rod-shaped. b. the water molecule has a negative charge at cold temperatures. c. water molecules have a positive charge on one end and a negative charge on the other.

Option (C) is the correct answer.

Explanation:

A water molecule is made up of two hydrogen atoms and one oxygen atom. Its molecular formula is .

It is known that hydrogen is electropositive in nature whereas oxygen is electronegative in nature. Therefore, oxygen will pull the electron of hydrogen towards itself as a result, there will be formation of partial positive charge on hydrogen and partial negative charge on oxygen atom.

Thus, the water molecule becomes polar. So, we can conclude that water molecule is a polar molecule because water molecules have a positive charge on one end and a negative charge on  the other.
