A) \[3d_{xy}^{1},3d_{yz}^{1},3d_{zx}^{1}\]
B) \[3d_{xy}^{1},3d_{yz}^{1},3d_{{{z}^{2}}}^{1}\]
C) \[3d_{({{x}^{2}}-{{y}^{2}})}^{1},3d_{{{z}^{2}}}^{1},3d_{zx}^{1}\]
D) \[3d_{xy}^{1},3d_{({{x}^{2}}-{{y}^{2}})}^{1},3d_{xz}^{1}\]
Correct Answer: A
Solution :
[a] Magnetic moment indicates that there are three unpaired electrons present in chromium. These must be present in lower energy orbitals which are \[3{{d}_{xy}},3{{d}_{yz}}\] and \[3{{d}_{xz}}\].
