The spin only magnetic moment of [ NiCl ₄ ]²⁻ is _____ (Nearest integer)

Correct answer

3

Step-by-step solution

Ni : 3 d^8 4 s^2 for the compound [ NiCl ₄ ]²⁻ , Ni is +2 oxidation state. Hence, the electronic configuration of Ni ²⁺ is given by Ni ²⁺: 3 d^8 Since, Cl ⁻¹ is a weak field ligand, so it will not cause pairing of electrons. So, for Ni ²⁺ the configuration is Hence, n=2 Spin only magnetic moment is given by aligned & _s= n(n+2) = 2(2+2) BM = 8 =2.82 BM & _s 3 ~B M aligned
