No, it depends on the electronegativity differences between the atoms involved in the bond. If the electronegativity difference between the two atoms involved in the bond is small, then the bond is non-polar and its arrangement around the central atom does not matter.
Dipole-dipole forces occur when their a great difference between the electronegativity of two atoms. When determining the dipole forces it is important to consider if they cancel or not because then polarity can be inferred.
Dipole-dipole forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule. Dipole-dipole forces have strengths that range from 5 kJ to 20 kJ per mole. They are much weaker than ionic or covalent bonds and have a significant effect only when the molecules involved are close together (touching or almost touching).
