Question

Given below are two statements:

Statement I: [Ni(CN)4]2– is square planar and diamagnetic complex, with dsp2 hybridization for Ni but [Ni(CO)4] is tetrahedral, paramagnetic and with sp3-hybridization for Ni.
Statement II: [NiCl4]2– and [Ni(CO)4] both have same d -electron configuration, have same geometry and are paramagnetic.

In light of the above statements, choose the correct answer from the options given below :

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is correct but Statement II is false
• D. Statement I is incorrect but Statement II is true

Answer 1

Answer: (B)

Both Statement I and Statement II are false

Answer 2

The correct answer is (B) : Both Statement I and Statement II are false.
$[Ni(CN)_4]^{2– }$is square planar and diamagnetic with μ = 0 , its hybridisation is dsp2
$Ni(CO)_4$ is tetrahedral but diamagnetic.
