1/2*(#Bonding e- - #antibonding e-)
Bond Order
Identify the orbitals below as bonding, non-bonding, or anti-bonding orbitals.
Anti-bonding Orbitals
Walsh diagrams
A representations of calculated orbital binding energies of a molecule versus a distortion coordinate
Predict the electron configution of of CH3- based on the correlation digram below.
1a12 1e4 2a12 (Counting the valence electrons and then predicting the most stable structure are the first two steps)
Predict the structure of CH3. based on the correlation digram below.
Planar (D3h) The energy gain by lowering of the 1e’ degenerate orbitals is greater than the energy loss by occupancy of a single electron in a2’’ and hence CH3 • is planar.
