dipole moment of water is 1.85 Debye
Induced dipole forces result when an ion or a dipole induces a dipole in an atom or a molecule with no dipole. These are weak forces. An ion-induced dipole attraction is a weak attraction that results when the approach of an ion induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species. A dipole-induced dipole attraction is a weak attraction that results when a polar molecule induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species.
A molecule has a net dipole moment if it has polar bonds arranged in such a way that they do not cancel each other out. For example, water (H₂O) has a bent shape, leading to a net dipole moment due to the difference in electronegativity between hydrogen and oxygen. In contrast, carbon dioxide (CO₂) is linear, and its polar bonds cancel each other, resulting in no net dipole moment. Therefore, to determine if a molecule has a net dipole moment, one must consider both its bond polarities and its geometry.
The more polar the molecule, the stronger the force.
Water is one of them
A dipole refers to two electrostatic charges which are separated by distance. In chemical compounds a dipole refers to unequal distribution of charge across a molecule that leads to an effective dipole often due to vector sum of bond dipoles.
From a physical standpoint, the dipole moment vector of a molecule is the net electric static force between the atoms. Assuming the molecule to be symmetrical, the vectors from the hydrogens toward the oxygen will cancel in the x-direction, leaving only a vector going from the center of the two hydrogens toward the oxygen.
Water (H2O) and ammonia (NH3) are examples of molecules that have a permanent dipole moment due to their asymmetrical molecular geometry. This means they have a positive end and a negative end, leading to an overall dipole moment.

Water is a polar molecule because it has a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atoms due to differences in electronegativity. This uneven distribution of charge creates a dipole moment in the molecule, making it polar.
Carbon dioxide is a linear molecule and any charges on the oxygens cancel each other out. emember vectors? Water is not linear the bent shape means that the charges on the H atoms do no cancel each other.
Yes, water is a dipole-dipole molecule because it has a polar covalent bond between the oxygen and hydrogen atoms, creating a partial positive and partial negative charge within the molecule.
An ion-dipole force is just how it sounds, an ion meets a molecule with a permanent electric dipole moment. An example would be Na+ with water, or Cl- with water, in an aqueous solution of NaCl.

Intermolecular attraction
The more polar the molecule, the stronger the force.
oxygen is more electronegative than nitrogen so we would expect a greater bond dipole for O-H as compared to N-H. Also water has two lone pairs whereas ammonia has only one. and these contribute to the net dipole moment.
