Rule 2 of VSEPR Model

Postby TiffanyL1G » Tue Nov 13, 2018 2:46 pm

In the textbook rule 2 states, "There is no distinction between single and multiple bonds: a multiple bond is treated as a single region of high electron concentration."
What exactly does it mean? Does that mean a single bond is simply a region with lower electron concentration? Does the electron concentration determine how many numbers of bonds there are?

This rule means that when determine molecular structure, a single-, double-, and triple- bond all are treated as the same number of electronic region (1 region each). A double-bond is not considered 2 regions of density when determining shape.

Singe, double, and triple bonds have the same effect for determining the shape of a molecule. The shape is not different depending on the order of the bond.
