JEE Main 2022Coordination Compounds Question with Solution

JEE Main 2022 (28 Jun Shift 1)

Question

Given below are two statements :

Statement I: NiCN42- is square planar and diamagnetic complex, with dsp2 hybridization for Ni but NiCO4 is tetrahedral, paramagnetic and with sp3 hybridication for Ni.

Statement II : NiCl42- and NiCO4 both have same d-electron configuration, have same geometry and are paramagnetic.

In light the above statements, choose the correct answer form the options given below
