Question

If x and y are total number of electrons which are present in non-axial and axial set of d-orbitals respectively in Ni cation of [Ni(DMG)2], then calculate value of $2x^2 / y$.

Correct answer: **ANSWER: 36**<BR>SOLUTION: NI2+ IN [NI(DMG)2] IS $3D^8$ AND $DSP^2$ HYBRIDIZED. DISTRIBUTION OF $D$-ELECTRONS: NON-AXIAL ORBITALS ($D_{XY}, D_{YZ}, D_{ZX}$) CONTAIN $2+2+2 = 6$ ELECTRONS, SO $X = 6$. AXIAL ORBITALS ($D_{Z^2}, D_{X^2-Y^2}$) CONTAIN $2+0 = 2$ ELECTRONS, SO $Y = 2$. THEREFORE, $2(6)^2 / 2 = 36$.
