Chemistry: Polar or non-polar? Dipolar moment?

Click For Summary

Discussion Overview

The discussion revolves around the polarity of a specific molecule and its dipole moment, exploring whether a molecule with a net dipole moment of zero can still be considered polar. The scope includes conceptual understanding and homework-related inquiries.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants assert that the molecule has triple symmetry, leading to a dipole moment of zero.
  • Others argue that despite the zero dipole moment, the molecule may still be polar due to the stronger electron attraction of oxygen compared to carbon.
  • A participant questions the relationship between dipole moment and polarity, suggesting that a molecule can have a null vector dipole moment yet still possess polar characteristics.
  • There is a reiteration of the concept that dipole moment is a vector quantity, which may influence the understanding of polarity.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between dipole moment and polarity, with no consensus reached on whether a molecule with a zero dipole moment can be classified as polar.

Contextual Notes

Participants discuss the implications of molecular symmetry and electron distribution, but the discussion lacks clarity on definitions and assumptions regarding polarity and dipole moment.

Homework Statement



Is this molecule polar or non polar? What is its dipolar moment?

Homework Equations





The Attempt at a Solution


The molecule has triple symmetry so its dipolar moment is 0. But I think it is polar because the oxygens atract the eletrons much more strongly than carbons.

Dipole moment is a vector.
 
yes i know, by 0 i meant null vector. so what's the answer?

If the net dipole moment is zero, is the molecule polar or non-polar?
 
that's my question, everyone treats dipole moment as a measure of polarity but I think it is possible for a molecule to have 0 dipole moment and be polar as the one in the figure. I think there is a negative pole in each oxygen even though the dipole moment is zero
