Hydrogen bonds are the intermolecular (present between molecules) interactions.
Hydrogen Bonding in Water (
Firstly, a water molecule contains two hydrogen atoms and one oxygen atom. The oxygen atom, being more electronegative, attracts the shared pairs of electrons more towards itself. As a result, oxygen gets a partial negative charge and hydrogen gets a partial positive charge.
Secondly, oxygen has two lone pairs of electrons. Moreover, hydrogen creates a strong electric field due to its small size. Thus, an oxygen atom of one
