Passage / Comprehension

Ligands are neutral or ionic species capable of donating at least one electron pair to central metal. Hence ligands can be of different denticities.

$[Mn (CO)_{5}]$ can attain more stability by :

Answer:

Solution:

E.A.N $= 25 - 0 + 2 \times 5 = 35$

here one electron is short to achieve inert gas configuration $[Mn (CO)_{5}] + e^{-} (Re duction) [Mn (CO)_{5}]^{-}$ EAN $= 36$

By dimerisation also

$[Mn_{2} (CO)_{10}] \Rightarrow EAN = 25 + 5 \times 2 + 1 = 36 [Kr]$
