JEE · NEET Previous Year Question

$The species that has a spin-only magnetic moment of 5.9 BM, is T_{d} = tetrahedral)$

Topic: JEE PYQ

Answer: A. Full step-by-step solution below.

A $[MnBr_{4}]^{2 -} (T_{d})$
B $[NiCl_{4}]^{2 -} (T_{d})$
C $Ni (CO)_{4} (T_{d})$
D $[Ni (CN)_{4}]^{2 -} (square planar)$

Correct answer: A

Solution

(a) [MnBr_{4}]^{2 -} \Rightarrow Mn^{2 +} \Rightarrow d^{5} (Td) d^{5} (Td) is high spin complex μ = 5 (5 + 2) = 5.91 B \cdot M
