A) \[{{d}^{2}}s{{p}^{3}}\]
B) \[s{{p}^{3}}{{d}^{2}}\]
C) \[s{{p}^{3}}\]
D) \[ds{{p}^{2}}\]
Correct Answer: B
Solution :
In \[{{[Ni{{({{H}_{2}}O)}_{6}}]}^{2+}}\] complex ion Ni is in +2 oxidation state, it has electronic configuration \[3{{d}^{8}}\]. Orbitais of \[N{{i}^{2+}}\] ions \[{{H}_{2}}O\] is a weak field ligand. So, pairing of electrons in d- orbitais does not occur. The complex \[{{[Ni{{({{H}_{2}}O)}_{6}}]}^{2+}}\] involves the outer 4d-orbitals for hybridisation\[(s{{p}^{3}}{{d}^{2}})\]. It is outer orbital complex. \[s{{p}^{3}}{{d}^{2}}\] hybridised orbitais of \[N{{i}^{2+}}\] \[{{[Ni{{({{H}_{2}}O)}_{6}}]}^{2+}}\]You need to login to perform this action.
