Water molecules have one oxygen atom that is more electronegative than the two hydrogen atoms bound to it. As a result, which type of bonding holds water molecules together?

A.) non polar covalent bonding

B.) polar covalent bonding

C.) ionic bonding

Answer: Option B.

Polar covalent bonding.

Explanation:

Hydrogen bonding or polar covalent bonding exist between water molecules. Water have one oxygen molecules that is electronegative and two hydrogen molecules that is slightly electropositive. Two hydrogen atoms are covalently bonded to one oxygen atom. In covalent bonding, there is sharing of electrons between atoms. In water, there is unequal sharing of electron between oxygen atom and hydrogen atoms. Oxygen atom tend to attract more electrons that hydrogen atoms, which make water a polar molecule.
