Chapter 5 - Bonding in polyatomic molecules Flashcards
Hybrid orbitals are generated by
mixing the characters of atomic orbitals that are close in energy.
The notation sp means that
one s atomic orbital and one p atomic orbital mix to form a set of two hybrid orbitals with different directional properties.

The number of ligand group orbitals formed =
the number of atomic orbitals used.
In MO theory, the first column under the point group symbol tells
the symmetry types of orbitals that are permitted within the specified point group.
In MO theory, the numbers in the column headed E indicate
the degeneracy of each type of orbital.
In MO, each row of numbers following a given symmetry label indicates
how a particular orbital behaves when operated upon by each symmetry operation.
