The realtive stabilities of metal carbonyls and their ions can be expl – InterviewSolution

1.	The realtive stabilities of metal carbonyls and their ions can be explained on the basis of a rule which is known as 18e^(-) rule. If number of valence shell electrons of the metal + number of electrons donated by bonded CO groups comes to be 18 electrons, then carbonyl is said to be stable. Which of the following complexes are following 18e^(-) rule?
