Dipole-dipole is between two polar molecules, that would be polar anyway.
Dipole-induced dipole is between a polar molecule and a non-polar molecule that is now polar due to the proximity of a polar molecule.
If you mean a dipole which only lasts for an instant, then you have to picture the electrons of the molecule surrounding the nuclei. In a non-polar molecule the electrons are shared evenly on average, but at any one second they may be distributed so that there is a greater density at one end than another, i.e. there is a temporary dipole.
The IMF of sulfur dioxide is London dispersion forces. This type of intermolecular force occurs between all molecules, regardless of their polarity, due to temporary fluctuations in electron density that create instantaneous dipoles.
Yes, sulfur dioxide (SO2) is a polar molecule and has a dipole moment. This is because of the difference in electronegativity between the sulfur and oxygen atoms, causing an unequal distribution of electron density within the molecule.
Br is one of those diatomic molecules that you'll have to remember. Br-Br is more stable than Br. If you mean bromine itself, then no, there is a 0 electronegativity difference. Dipole moments are, by rule of thumb, generally from EN differences of 0.4 to 2.0. Anything before 0.4 is considered nonpolar/covalent bonded and anything over 2.0 is considered ionic.
The main interactions between molecules of hydrogen chloride are dipole-dipole interactions. Hydrogen chloride is a polar molecule with a partially positive hydrogen end and a partially negative chlorine end. These partial charges attract neighboring hydrogen chloride molecules, resulting in dipole-dipole interactions.

London dispersion forces (instantaneous induced dipole-dipole interactions.)
A ball-and-stick model for NOCl is given below:This is a polar molecular compound. Therefore, the intermolecular forces include dipole-dipole forces and dispersion forces.Dispersion forces are also called London forces, induced dipole-induced dipole forces, or instantaneous dipole-induced dipole forces.

Examples of dipole-induced dipole forces include the interaction between a polar molecule (with a permanent dipole moment) and a nonpolar molecule (with an induced dipole moment) or the interaction between a polar molecule and a nonpolar atom. This type of interaction leads to a temporary polarization in the nonpolar molecule or atom due to the presence of the polar molecule, resulting in a weak attractive force between them.
The main forces between molecules of CS2 are London dispersion forces and dipole-dipole interactions. CS2 is a nonpolar molecule because the sulfur-carbon and carbon-sulfur bonds are symmetrical, resulting in weak forces of attraction between the molecules.
Ion-dipole, Dipole-dipole, and Dipole-induced dipole.
Dispersion forces are forces that are due to certain distortions in the electron density around atoms or moleculed. They can be mainly categorized in to : 1.Induced dipole-induced dipole forces 2.Dipole dipole force 3.Induced dipole-dipole forces 4.London force Dipole forces are forces between molecules that have permanent dipole character like NaCl.However, in cases like certain molecules that do not have dipole character, there may be instantaneous distotions which leads to london forces.Dipoles can induce dipole character by thickening densities of electrons around certain atoms, leading to induced dipole interactions.
Debye forces are those between a permanent dipole/multipole and an induced dipole. Keesom forces are Boltzmann-averaged forces between permanent dipoles. "Keesom forces" is a considerably more obscure term, by the way. I actually had to look it up. They're generally just referred to as "the dipole-dipole interaction" and the Boltzmann-averaged part is taken as obvious.
An example of dipole-induced dipole forces is the interaction between a polar molecule, such as water, and a nonpolar molecule, such as nitrogen. The polar molecule induces a temporary dipole in the nonpolar molecule, creating an attractive force between the two molecules. This type of interaction helps explain why some substances can dissolve in water even if they are nonpolar.
Van der Waals forces are usually considered to includedipole - dipole interactionsdipole- induced dipole interactionsinstantaneous dipole - induced dipole interactions (London dispersion forces)These are electrostatic in nature, and cause an attraction between molecules
They vary depending on the molecules under consideration. They are all electrostatic in nature deriving from the interaction of permanent or instantaneous dipoles. They are lumped together as Van der Waals forces but can be considered to be of 3 types:-Keesom forces permanent dipole dipole interactionsDebye forces; permanent dipole interaction with induced dipole,London dispersion forces ; interaction between two instantaneous dipoles.
Dispersion forces are formed between two non-polar molecules. These molecules form temporary dipoles. This creates a weak force. Dipole Dipole forces have a permanent dipole. That is the basic explanation
