Concept #1: The 18 and 16 Electron Rule

Example #1: What is the electron count of the neutral transition metal complex of Br2Pd(CO)2?

Example #2: What is the electron count of the neutral transition metal complex of Pd(en)2?

Practice: How many NH­3 ligands would need to be placed onto a nickel atom if we assume the resulting complex follows the 18-electron rule?

Practice: Using the 18-electron rule, explain why V(CO)6 can be easily reduced to [V(CO)6]–.
