Difference between electron geometry and molecular geometry

Postby Claire_Kim_2F » Thu Dec 03, 2020 7:28 pm

Good afternoon,
I was wondering what the difference between the electron and molecular geometry was?

Electron geometry basically describes the arrangement of electron groups while molecular geometry describes the arrangement of atoms in relation to the central atom. Hope that helps!

Exactly what Madilyn said, but keep in mind that we will only be tested on molecular geometry, and whenever the shape is asked we are talking about the position of the atoms. Hope this helps!

It's also important to note that the placement of both atoms and lone electrons helps determine the molecular geometric shape. This is because the location of the lone electron pairs can change the bond angles between atoms (the electrons have a greater repulsion than bonded atoms).

Hi!

Electronic geometry takes into account all the bonding pairs as well as lone pairs on the central atom. molecular geometry only looks at the bonding pairs.

the difference is that electron geometry takes into account all regions of electron density, so lone pairs, and atoms, while molecular geometry only accounts for atoms to determine shape.
