Question

practice: dipole - dipole forces 3
you said that the molecules to the right were polar.
do you think that means theyll have dipole - dipole interactions with the polar molecule h₂s or not? and if so, why?
yes. polar molecules experience dipole - dipole interactions with other polar molecules.
no. polar molecules arent all the same. sometimes they can have dipole - dipole interactions with other polar molecules, but sometimes they cant.

Explanation:

Dipole - dipole interactions occur between polar molecules. Since the molecules in question are polar and \(H_2S\) is also a polar molecule, they will experience dipole - dipole interactions. The key concept is that polar molecules have a permanent dipole moment (due to differences in electronegativity within the molecule), and these dipoles can attract each other. One polar molecule's positive end is attracted to another polar molecule's negative end.

Answer:

Yes. Polar molecules experience dipole - dipole interactions with other polar molecules.
