Both of the H are always positive. The O is negative.
look at the image and see which has the 2 H+ and O-
Polar Covalent
A molecule with hydrogen bonded to O, N, or F (Apex)
Water molecules are held together by hydrogen bond which is formed between hydrogen of one molecule and oxygen of other molecule. H2O-----H-O-H
Hydrogen-bonding molecules
the intermolecular forces present in methanol are hydrogen bond between the oxygen and hydrogen part of the molecule and van der waals forces between the carbon and hydrogen part of the molecule.
hydrogen bonding Oxygen attracts electrons much more strongly than hydrogen, resulting in a net positive charge on the hydrogen atoms, and a net negative charge on the oxygen atom. The presence of a charge on each of these atoms gives each water molecule a net dipole moment,. Electrical attraction between water molecules due to this dipole pulls individual molecules closer together. This attraction is known as hydrogen bonding. The molecules of water are constantly moving in relation to each other, and the hydrogen bonds are continually breaking and reforming very very fast in nanoseconds..
hydrogen bonding between H2O and covalent bonding within the H2O molecule
inter molecular hydrogen bonding is between one molecule and the neighbouring molecule whereas the intra molecular bonding between the same molecule
hydrogen bonding between base pairs
hydrogen bonding
The hydrogen molecule, H2, consists of two hydrogen atoms joined by a covalent bond in which one pair of electrons is shared. The hydrogen molecule does not experience hydrogen bonding, as it is a nonpolar molecule.
Within the molecule itself, water exhibits ionic bonding. Between the water molecules, there is hydrogen bonding.

Water molecules are held together by hydrogen bond which is formed between hydrogen of one molecule and oxygen of other molecule. H2O-----H-O-H
Hydrogen bonding is usually formed between one lone pair of electrons of the oxygen atom of one water molecule and the hydrogen atom of another water molecule. Hydrogen bonding forms as a result of electro-negativity difference between oxygen atom and hydrogen, with oxygen being more electro-negative.
A common example of hydrogen bonding is the one between water molecules.Hydrogen bonding is an intermolecular type of bonding, so it occurs when the hydrogen of one molecule is attracted to the lone pairs of either Oxygen, Nitrogen or Fluorine because of their high electronegativity. Since water has two hydrogen atoms bonded to an oxygen atom with lone pairs, the hydrogen bonds occur when a hydrogen of one water molecule is attracted to the lone pairs on another water molecule.what else can you give me on hydrogenHydrogen bonding takes place between the hydrogen and oxygen.
