Vedclass · Answer

(D) The $EAN$ of $Co(CO)_4$ is calculated as: $27 + (4 	imes 2) = 35$. Since this is not equal to the atomic number of the next noble gas $(36)$,it does not follow the Sidgwick $EAN$ rule. It can attain stability by gaining one electron (reduction of $Co$) to form $[Co(CO)_4]^-$,or by dimerization to form $Co_2(CO)_8$,where each $Co$ atom effectively shares an electron through a metal-metal bond,resulting in an $EAN$ of $36$ for each $Co$ atom.

The Effective Atomic Number $(EAN)$ of $Co(CO)_4$ is $35$,hence it is less stable. It attains stability by:
