Name of Molecule
How do we know when to ignore the lone pair electrons when naming the molecule? Because this can change a trigonal pyramidal to a trigonal planar correct?

Re: Name of Molecule
Like for example I3-, I'm confused whether this is linear or a trigonal bipyramidal

Re: Name of Molecule
I'm pretty sure you are never supposed to ignore the lone pairs when naming a molecule.

Re: Name of Molecule
Lone pairs actually greatly affects the shape. For example a trigonal planar becomes a trigonal pyramidal if there is a lone pair on the central atom.

Re: Name of Molecule
Lone pairs affect shape even more than bonds (as seen by their ability to reduce bond angles like turning a bond angle of 120 degrees to <120) so they cannot be ignored
