JEE Main 2022 — Coordination Compounds Question with Solution
From: JEE Main 2022 (Online) 28th June Morning Shift
Question
Given below are two statements :
Statement I : [Ni(CN)4]2 is square planar and diamagnetic complex, with dsp2 hybridization for Ni but [Ni(CO)4] is tetrahedral, paramagnetic and with sp3-hybridication for Ni.
Statement II : [NiCl4]2 and [Ni(CO)4] both have same d-electron configuration have same geometry and are paramagnetic.
In light the above statements, choose the correct answer from the options given below :
