Chemistry: Polar or non-polar? Dipolar moment?

[tsuwal]

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?

 

[tsuwal]

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
