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). The figures show two arrangements of polar iodine monochloride (ICl) molecules that give rise to dipole-dipole attractions.Note: 1  Polar molecules have a partial negative end and a partial positive end. 2  The partially positive end of a polar molecule is attracted to the partially negative end of another.hey 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).
