Q
What does the valence shell electron pair repulsion theory state? (VSEPR)
A
Electron pairs as far away as possible from each other determines the shape of the molecule.
1
Q
What do Lewis structures NOT tell us?
A
- the 3D shape of the molecule
- the sorts of orbitals the electrons are in when molecule formed
2
Q
What does the valence bond theory say?
A
In making a bond between two atoms, half-filled atomic orbitals, in which valence electrons from each atoms lie, overlap to make a new orbital in which the pair of electrons exist.
3
Q
What do hybrid orbitals always lead to?
A
Sigma bonds
