Basic Principles for Construction of Qualitative Molecular Orbital Diagrams (LCAO - MO's) 1. In order for two atomic orbitals to form a molecular orbital, they must have the same symmetry about the internuclear axis. Moreover, each possible MO must form a basis for some irreducible representation of the point group of the molecule. 2. The magnitude of the interaction (stabilization of bonding MO's and

Unformatted text preview: destabilization of antibonding MO's) depends on the overlap and energy difference between the composite atomic orbitals. • interaction increases with increasing overlap • interaction decreases with increasing energy difference of AO's 3. The number of molecular orbitals obtained (bonding, nonbonding and antibonding) is equal to the number of composite atomic orbitals....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
