Specifying molecular geometry

[Joshua Xian 1D]

For molecular geometries that are both called the same thing but have different origins in terms of electronic geometry (e.g. bent molecular geometry can be from 3 or 4 regions of electron density, trigonal planar and tetrahedral electronic geometries respectively), do we need to specify which electronic geometry that the molecular geometry came from?

[Zane Mills 1E]

In most cases no, unless it is specified in the question. Most times when asking for molecular geometry they simply require the geometry of the molecule as is

[Mitch Mologne 1A]

I would venture to say you will never have to verify the derivation of the molecular structure, but rather just what it is.

It's definitely helpful to know the overall electron geometry for each molecule, though, because it can allow you to better see the overall shape that is manipulated when atoms are replaced with lone pairs!
