Green coloured $\mathrm{Ni}(\mathrm{PPh}_{2}\mathrm{Et})_{2}\mathrm{Br}_{2}$, has a magnetic moment of 3.20 B.M. The geometry and the number of isomers possible for the complex respectively, are
(a)Square planar and one
(b)Tetrahedral and one
(c)Square planar and two
(d)Tetrahedral and two
Answer
Answer: B ✓ checked by 4AB · confidence high
Explanation
3.2 BM means two unpaired electrons: tetrahedral Ni(II). A tetrahedral MA₂B₂ complex has no geometric isomers — one form.
