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. ... The partially positive end of a polar molecule is attracted to the partially negative end of another.

Which has dipole-dipole interaction?

Dipole interaction is said to occur between a polar group on the polymer molecule, for example a chlorine atom forming part of a carbon–chlorine dipole, and a polar group on the plasticiser, for example an ester group.

How do you know if something has dipole dipole forces?

You have a dipole moment when there is a difference in electronegativity between two atoms.
