Question

What causes hydrogen bonding between water molecules? covalent bonds between water molecules, difference in electronegativity between the oxygen atom and hydrogen atoms, oxygen atoms contain more electrons than hydrogen atoms, ionic bonding

Answer 1

The answer should be the difference in electro negativity because all atoms want to become equal in respect with their charges and an oxygen has a -2 charge and a hydrogen is +1 so 2 hydrogen bonding with 1 oxygen makes and equal charge.
