Gonna try and describe this the best I can

^really hope it helps :)
There are two allowed structures of SF4Cl2... the cisform where one chlorine is in an equitorial position and one is axial, and the trans form where both chlorines are in axial positions. In the trans form the S-F bond dipoles all cancel each other, as do the S-Cl bond dipoles, because they are opposite each other. Therefore the molecule is non-polar. In the cisform, two of the S-F bond dipoles cancel, but because the other S-F bond dipoles are across from S-Cl bond dipoles, they do not cancel (S-F is more polar than an S-Cl bond). Therefore, the cisform is polar.
The dipole moment tells us that there is net dipole on the molecule which indicates that any dipoles due to polarity of the covalent bonds do not cancel each other out. For example H2O has a dipole moment which rules out a linear structure where the bond dipoles would cancel each other out.
The strongest intermolecular attraction in ethane is London dispersion forces. These forces are caused by temporary fluctuations in electron distribution, leading to temporary dipoles in neighboring molecules.
A good clue is to look at the symmetry of the molecular geometry. Molecules that are not symmetric are polar.In a bond, the more electronegative atom attracts a bigger share of the shared electrons than the other. This separation of charge results in a bond dipole. When all the bond dipoles of a molecule are added, the net dipole is called the permanent dipole moment. When the bond dipoles cancel, the molecule's dipole moment is zero and the molecule is called nonpolar. If the bond dipoles do not cancel, the molecule is polar.Lone pairs contribute to the polarity of a molecule. Since there is no positive nucleus to offset the negative charge of the lone pair, the end with the lone pair will always have a higher partial negative charge than any atom.The key to determining whether or not dipoles cancel is to consider their direction as well as their magnitude. The direction is determined by the molecular geometry. The Lewis structure does not represent the molecular geometry.
CO2 , carbon dioxide (2 linear, opposite dipoles O=C=O)
A molecule with two strong bond dipoles can have no molecular dipole if the bond dipoles cancel each other out by pointing in exactly opposite directions. For example, in carbon dioxide (a linear molecule), the carbon-oxygen bonds have a large dipole moment. However, because one dipole points to the left and the other points to the right, the dipoles cancel and overall there is no molecular dipole.

Covalent bonds involve the sharing of electrons between atoms, creating a strong bond due to the overlap of electron clouds. In contrast, the electrical attraction between neighboring molecules, such as in van der Waals forces, is weaker because it involves temporary dipoles that are easily broken. The strength of a covalent bond is determined by the shared electrons holding the atoms together.
The strongest intermolecular attraction in ethane is London dispersion forces. These forces are caused by temporary fluctuations in electron distribution, leading to temporary dipoles in neighboring molecules.
To calculate the dipole moment of a molecule, you need to determine the magnitude and direction of the individual bond dipoles within the molecule. The dipole moment is the vector sum of these bond dipoles. It is calculated by multiplying the magnitude of each bond dipole by the distance between the charges and then adding up all the individual bond dipole moments to get the total dipole moment of the molecule.
bond polarity is the polarity particular bond within a molecule, while molecular polarity is the polarity of the whole molecule. take for example water (H20): you could find the bond polarity of each H-0 bond (polar covalent), or the polarity of the whole molecule together (polar, because the electronegativity of oxygen is higher than the hydrogen atoms)
The three parts of a bond is atoms, molecules, and ions. The three parts of a bond is atoms, molecules, and ions. The three parts of a bond is atoms, molecules, and ions.
Symmetric molecules, such as diatomic molecules like O2 and N2, as well as molecules with symmetrical geometry like CO2, generally do not have a dipole moment because the individual bond dipoles cancel each other out.
HBr primarily exhibits dipole-dipole interactions due to the polarity of the H-Br bond. Additionally, HBr can also experience dispersion forces, caused by temporary dipoles that occur in all molecules.
No, an ionic bond is not a dipole-dipole force. Ionic bonds form between ions of opposite charges, resulting in the attraction between positive and negative ions. In contrast, dipole-dipole forces occur between molecules with permanent dipoles due to unequal sharing of electrons.
