Type of bonding in water :- Polar covalent bonding.
Bond is formed hydrogen and oxygen by mutual sharing of electrons, so it is a covalent bond.
In water molecule, the oxygen atom attracts the shared electron pair towards itself because of higher electronegativity, thereby developing a slight negative charge on it.
On the other hand, a slight positive charge develops on the hydrogen atoms.
Therefore, a polar covalent bond is formed.
