regions of e- density

Postby danielruiz1G » Thu May 31, 2018 11:41 pm

do the number of regions of electron density always directly correspond to molecular shapes or are there exceptions?

I believe the different regions of electron density do correspond to different molecular shapes because it was said in class that different hybridizations describe shapes. I this would connect to your question because the regions of electron density= number of hybrid orbitals. Hope it helped.

Yes, regions of e- density can either be bonds or lone pairs, and both affect the shape of a molecule. Lone pairs especially affect structure because they have large repulsion forces, and they can decrease bond angles by repelling atoms away more strongly than a normal atom would do.

in addition, multiple bonds are treated as equal to single bonds; i.e. a double bond does not have more repulsion than a single bond.

yes since these regions determine the orientation of forces on the atoms within the molecule and thus how they conform to make the shape of the molecule
