Vedclass · Answer

(B) The atomic number of $Ni$ is $28$. The electronic configuration of $Ni$ is $[Ar] 3d^8 4s^2$.In the complex $[Ni(CO)_4]$,the oxidation state of $Ni$ is $0$.$CO$ is a strong field ligand $(SFL)$,which causes the pairing of electrons in the $3d$ orbital.The $4s$ electrons are promoted to the $3d$ orbital,and the $4s$ and $4p$ orbitals undergo $sp^3$ hybridisation.Since all electrons are paired,the complex is diamagnetic.The $sp^3$ hybridisation results in a tetrahedral geometry.

List-$I$	List-$II$
$A. K_2[Ni(CN)_4]$	$I. sp^3$
$B. [Ni(CO)_4]$	$II. sp^3d^2$
$C. [Co(NH_3)_6]Cl_3$	$III. dsp^2$
$D. Na_3[CoF_6]$	$IV. d^2sp^3$
