Can an octahedral be polar?

Postby Anna O 2C » Mon Nov 26, 2018 7:10 pm

I'm looking for examples of polar molecules with an octahedral shape and I'm struggling to find any. Is there an exception saying that octahedral shapes are usually nonpolar or are there any good example of octahedral structures that are polar? Thanks!

No. The octahedral shape is always nonpolar, because the shape is symmetrical. When a molecule has a symmetrical shape, the dipoles cancel out and the molecule in nonpolar.

If a central atom has 6 regions of electron density surrounding it and they're all other atoms, then it will be nonpolar, but if there's one or more lone pair on the central atom then the shape is no longer symmetrical and could be polar.

The octahedral shape is almost always non polar because it is symmetric, causing the dipole moments to cancel one another. Hope this helps!

No, an octahedral cannot be polar, because the shape is symmetric
