    Which of the following is not a metal carbonyl?

    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?

    Assertion: van method is used to prepare ultrapure samples of some metals. Reason: It involves reaction of CO with metals to form volatile carbony,s which decompose on heating to give pure metal.

    In metal carbonyls, there is synergic bonding interaction between metal and carbon monoxide. This leads to increase in strength of metal ligands bond and decrease in bond order of CO in carbonyl complex as compared to bond order in carbon monoxide. Simple carbonyls are invariably spin-paired complexes except for vanadium metal. Which one of the following metal carbonyls are inner orbital complexes with diamagnetic property ?
