When 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?

Water molecules are held together by hydrogen bonding. This occurs because the oxygen atom, being more electronegative, creates a partial negative charge, while the hydrogen atoms acquire a partial positive charge. These polar characteristics allow the positively charged hydrogen atoms of one water molecule to attract the negatively charged oxygen atoms of neighboring water molecules, forming hydrogen bonds.
