dipole dipole

[lauraxie2e]

does a molecule have to be polar to have dipole dipole IMFs

[Chem_Mod]

Yes, dipole is permanent and is due to a difference in electronegativity between atoms forming a polar molecule.

[Lara Kristine Bacasen 1L]

Yes, just remember that dipoles are the partial charges that arise in polar molecules and these dipoles interact with each other. Thus the name dipole dipole.

[DMuth_1J]

both molecules must be polar, not just one. Otherwise it would be a dipole - induced dipole

[Natalie Nartz 4F]

Yes, the partial charges created by the dipoles makes the molecule polar

[605208780]

Yes. Both of the molecules have to be polar. The partial charges created by the dipoles makes it polar.

[105335337]

Yes. Dipole-Dipole IMFs means that both of the molecules have a dipole moment.

[Kishan Shah 2G]

Yes. The molecule needs to be polar in order to for it to have dipole dipole interactions since the dipole on one molecule can form an IMF with the dipole on the other molecule.
