Question

Hybridisation, shape and magnetic moment of $ {{[Ni{{(CN)}_{4}}]}^{2-}} $ ion

• A. $ ds{{p}^{2}}, $ square planar, zero
• B. $ ds{{p}^{2}}, $ square planar, 1.73
• C. $ s{{p}^{3}}{{d}^{2}}, $ octahedral, zero
• D. $ {{d}^{2}}s{{p}^{3}}, $ octahedral, 1.73

Answer 1

Answer: (A)

$ {{[Ni{{(CN)}_{4}}]}^{2-}} $ ion has $ ds{{p}^{2}} $ hybridisation, zero magnetic moment and square planar structure.
It has no unpaired electron hence, its magnetic moment is zero.
