A student claims that the presence of hydrogen bonds between water molecules is due to even sharing of electrons in non-polar covalent bonds. What's the flaw in this statement?
O Water molecules do not form hydrogen bonds.
O Hydrogen bonds in water arise due to uneven sharing in polar covalent bonds.
O Water molecules form ionic bonds, not covalent.
O Water molecules only form covalent bonds with other elements, not with other water molecules.

Answer:

"Hydrogen bonds in water arise due to uneven sharing in polar covalent bonds."

Explanation:

Water molecules are made up of polar covalent bonds, which means the shared electrons are not shared evenly, creating a partial positively charged side, and a partially negatively charged side, which is a dipole.

These molecules are attracted to each other because they have dipoles, so one molecule's negative dipole will gravitate towards another molecule's positive dipole. These are called hydrogen bonds because they are a dipole attraction between hydrogen and oxygen, and oxygen is a very electronegative atom. Hydrogen bonds also occur with fluorine and nitrogen because they are also very high in electronegativity. The attraction between each water molecule is not a polar covalent bond, but it is because of water molecules containing polar covalent bonds that there is an intermolecular force called hydrogen bonding that keeps these molecules together.
