Molecular Geometry and polarity

Postby Adrian C 1D » Fri Nov 30, 2018 3:06 pm

If a molecule's molecular geometry is linear, is it a good indicator of the molecule being nonpolar?

Depending on the electronegativity of the atoms or molecules, it should be a good indicator that it is nonpolar.

Not necessarily, e.g. HCN is linear, but polar

It depends - if atoms of two different elements are attached to the central one, then it will be polar.

It will only be non polar if the two outside atoms are identical.

if the two atoms attached are the same, then yes. But if they are different, then the dipoles may not cancel and you could have a polar molecule.
