Points to Consider
We have looked very briefly at where electrons are in covalent bonds.
- How does the location of the electron in a bond influence the three-dimensional geometry of that molecule?
- What modifications do we have to make to our understanding of orbitals in order to explain some details of
covalent bonding?
