Inside a single water molecule (between hydrogen and oxygen), the atoms are held together by covalent bonds, specifically polar covalent bonds.

Quick Scoop

  • The O–H bonds inside a water molecule are polar covalent, meaning electrons are shared but pulled closer to oxygen due to its higher electronegativity.
  • Hydrogen bonds occur between separate water molecules (from a hydrogen on one molecule to an oxygen on another), not as the primary bond holding H and O together in the same molecule.
  • So, from the options “hydrogen bonds, electronegative bonds, proton bonds, covalent bonds,” the correct answer for the bond inside the water molecule between hydrogen and oxygen is: covalent bonds.

Think of it like this: covalent bonds are the “internal glue” holding each H₂O molecule together, while hydrogen bonds are the “Velcro” linking one water molecule to its neighbors.

TL;DR: The bond between hydrogen and oxygen within a water molecule is a polar covalent bond.
