Vedclass · Answer

(C) The stability of metal carbonyls is often governed by the $18$-electron rule or the $EAN$ (Effective Atomic Number) rule,which states that the complex is most stable when the total number of electrons equals the nearest noble gas configuration ($36$ for $Mn$ series).$1$. For $[Mn(CO)_6]^+$,the $EAN$ is $25 - 1 + (6 	imes 2) = 36$,which is stable.$2$. For $[Mn(CO)_6]$,the $EAN$ is $25 + 12 = 37$. This species has one extra electron compared to the stable $36$-electron configuration.$3$. Therefore,$[Mn(CO)_6]$ tends to lose an electron to achieve the stable $36$-electron configuration: $[Mn(CO)_6] ightarrow [Mn(CO)_6]^+ + e^-$.$4$. Since it loses an electron,it acts as a reducing agent.

Which of the following species can act as a reducing agent?
