Molecules of Water Stick to Each Other Because

Question

Molecules of water stick to each other because:
A) hydrogen bonds form between the hydrogen atom of one molecule and the oxygen atom of another molecule.
B) water molecules are nonpolar, and nonpolar molecules stick together.
C) hydrogen bonds form between the hydrogen atom of one molecule and a hydrogen atom of another molecule.
D) covalent bonds form between the hydrogen atom of one molecule and the oxygen atom of another molecule.

Accepted Answer

Water molecules are polar, meaning they have a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atoms. This polarity allows for hydrogen bonding to occur between water molecules, where the partially positive hydrogen of one molecule is attracted to the partially negative oxygen of another molecule. This bond is not as strong as a covalent bond, but it is strong enough to cause water molecules to stick together, which is why water has a high surface tension and can form droplets.
