The hybridization involved in complex N i C N 4 2 - is: (Atomic number of Ni = 28)
Options
- Ad s p 2
- Bs p 3
- Cd 2 s p 2
- Dd 2 s p 3
Correct answer
A. d s p 2
Step-by-step solution
N i C N 4 2 - Oxidation state of Ni is +2 x - 4 = 2 x = + 2 Now, Ni 2 + = [ Ar ]   3 d 8   4 s ° therefore, CN - is a strong field ligand. Hence, all unpaired electrons are paired up. therefore, hybridisation of Ni ( CN ) 4 2 - is dsp 2
