Discussion Overview

The discussion revolves around understanding intermolecular forces, specifically focusing on permanent dipole-permanent dipole (pd-pd) interactions and induced dipole-induced dipole (id-id) interactions. Participants express confusion regarding the identification of these forces and seek clarification on related concepts such as molecular shapes.

Discussion Character

  • Exploratory, Conceptual clarification, Homework-related

Main Points Raised

  • One participant expresses confusion about pd-pd and id-id bonds, linking them to polar molecules but feeling lost in understanding.
  • Another participant suggests that molecules with permanent dipoles can engage in pd-pd bonds, while those without can only rely on id-id interactions.
  • A request for clarification on what constitutes a permanent dipole is made by a participant.
  • A link to a Wikipedia article on dipoles is provided as a resource for further information.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there is ongoing confusion and requests for clarification regarding the concepts discussed.

Contextual Notes

There are limitations in the discussion, such as the lack of definitions for key terms and the need for further explanation of molecular shapes, which are not fully addressed.

TL;DR
I cannot understand what are pd-pd and id-id forces.
I cannot understand what are pd-pd and id-id bonds along with how to identify them. I think this is related to something about polar molecules but I’m just really lost right now.


I also need help on how to remember the names of the different shapes that the compounds form; e.g - Trigonal Planer.

If the molecule has a permanent dipole, it can participate in pd-pd bonds, if it doesn't have the permanent dipole - induced dipoles is the only thing it can count on.

Can you please explain what permanent dipoles are?
