The more polar the molecule, the stronger the force.

∙ 14y agoAny separation of charge is a dipole. A permanent dipole results from an unequal distribution of charge eg. in a covalent bond. A covalent bond between two of the same atoms is not a permanent dipole. But a covalent bond between two different atoms is a permanent dipole. However, if the difference in electronegativity is < 0.5, the dipole can be said to be insignificant. This means that C-H bonds are non-polar. This is convenient in explaining why hydrocarbons do not dissolve in water. It should be noted that a molecule can have many dipoles operating in different directions but no overall dipole or an insignificant overall dipole.

∙ 10y agoOne can determine the polarity of a magnet quite easily. It's as simple as tying a string around the magnet around the center, and then holding up the magnet on the string so it can turn free. The magnet will point to either the south or the north, determining polarity.

How do van der Wals forces hold molecules together?
When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Apex------They form temporary, weak dipole attractions between molecules.
What affects the size of the magnetic moment of a diatomic molecule?
Without the full quantum mechanical treatment let's look at an atom. In all atoms, the electrons are in motion, and are creating magnetic fields around their paths of travel. And each electron is in a specific orbital (Fermi energy level) and will have an associated angular momentum unique to that specific orbital. To discover the atomic (magnetic) dipole moment, we have to gather up and add the spins of each of the electrons, and also find and sum each orbital angular momentum where an electron is operating. With the spins of the electrons and the angular momenta of the orbitals, we can then combine those to discover the total angular momentum. From there, it's a hop, skip and a jump to find the magnitude of the atom's dipole moment. In a molecule, we have to do this for multiple atoms. Additionally we have to make accommodations for the magnetic moments of any unpaired electrons. We must also account for nuclear spin configuration and the energy state of the molecule to arrive at the magnitude of the magnetic moment. We might have to consider nuclear magnetism in the isotopes of some elements, but these are the basic variables that must be managed to find the magnitude of the magnetic moment of a molecule. A link can be found below to check facts and review the mathematics involved.

What is the electronegativity of H2S?
If you can't find the dipole moment online then you can get a pretty good approximation using the following method though it is a bit involved. You will need the following two pieces of information before you begin, which I have obtained from Chemistry, The Central Science by Theodore Brown 11e:Electronegativities (EN) of Se and H: 2.4 and 2.1, respectively.The bonding radii of the Se and H atoms: 1.16 and 0.37 Å (E-10 m), respectively.To find the dipole moment you must first find the partial charge of the Se and H atoms. This is the amount by which the bonding electrons are shared unequally:EN(Se)/[EN(Se) + EN(H)] x 2e = amount of the bonding electrons that pertain to Se= 2.4/(2.4 + 2.1) x 2e = 1.07e → ±0.07eSe holds a partial charge of -0.07e and H holds a partial charge of +0.07ee = charge of an electron = 1.602 E-19 coulomb (C)Next, we find the length of the Se-H bond by simply adding their bonding radii:(1.16 + 0.37)E-10 m = 1.53E-10 mFinally, we multiply the separated charge by the distance of separation, where the displacement vector d is directed from the negative to positive charge, to obtain the dipole moment:μ = q x d = 0.07(1.602E-19 C) x 1.53E-10 m = 1.7E-30 C-mThe molecular dipole moment of H2Se is the sum of the individual Se-H dipole moments. If we place the Se atom at the center of an xy plane, i.e., at the point (0,0), and the two H atoms either above or below the Se atom then we can see that the xcomponents of the two Se-H dipoles cancel each other as their magnitudes are the same, but in an opposite direction. The ycomponents of the two vectors, however, are in the same direction so they add and because they are the same magnitude their sum is simply twice the magnitude of one of them and its direction exactly bisects the molecule.The magnitude of the y component of one vector is found by taking half of the H-Se-H bond angle, which for a bent molecule is ~104.5°, and multiplying the magnitude of the dipole moment by cosine of half of the angle:y component = 1.7E-30 C-m x cos(52.25) = 1.0E-30 C-mTwice this amount gives the net dipole moment of H2Se = 2.0E-30 C-m
