Tetrachlorocyclopropene polarity
« on: December 03, 2018, 09:48:58 PM »
Is this molecule polar? I believe it's non-polar because the net polarity on the Cls on the wedge and dash is upwards (assuming that both Cls are angled upwards and downwards at the same angle). As a result, the net polarity is 0 (since they are 120 degrees to each other)

Another camp is the polar camp and believes the molecule is polar, because the Cls on the wedge and dash are not on the same plane.

Do you think tetrachlorocyclopropene is polar or non polar?

You considered only a polarisation perpendicular to the plane. Why? And are the Cl the only cause of polarisation?

By the way, I didn't check if said compound exists long enough to measure something.

It's remarkably stable, you can make hundreds of grams of the stuff, or even buy it from sigma https://www.sigmaaldrich.com/catalog/product/aldrich/145947?lang=en&region=US
