Type: MCQ-conceptual-Hard-Class 12

Among [Ni(CO)₄], [Ni(CN)₄]²⁻, [NiCl₄]²⁻ species, the hybridization states at the Ni atom are, respectively :- (At. No. of Ni = 28)

A

sp³, dsp², sp³

B

sp³, sp³, dsp²

C

dsp², sp³, sp³

D

sp³, dsp², dsp²

Correct Answer

Option A

Detailed Explanation

[Ni(CO)₄] is sp³ hybridized, [Ni(CN)₄]²⁻ is dsp² hybridized due to strong field ligand causing pairing, and [NiCl₄]²⁻ is dsp² hybridized.
