NOTE: The an0bonding orbitals are not shown in this diagram but should be included as well if they need to be consider. Walsh Diagram for EH3 Extending to AH4 For AH4, the two arrangements possible (for this class) are square planar and tetrahedral. Star0ng with square planar follow through the steps for developing the MO diagram. Step 1: point group D4h Step 2: Assign z axis as the highest order rot...
