Given that the expected spin-only magnetic moment for $\left(\mathrm{Et}_{4} \mathrm{N}\right)_{2}\left[\mathrm{NiCl}_{4}\right]$ is $2.83 \mu_{\mathrm{B}}$, the total number of unpaired electrons in this complex is ____ .
Answer
Answer (as printed): 2

The options are missing from the source scan for this question, so there is nothing here for this letter to point at. The letter is what the book printed.

Explanation
Answer: 2 — μ = √(n(n+2)) = 2.83 → n = 2 (tetrahedral Ni²⁺ d⁸).
