The hybridization involved in complex [Ni (CN) _ 4 ] ^ 2 - is:...

The hybridization involved in complex [Ni(CN)4]2−{\left[Ni{\left(CN\right)}_{4}\right]}^{2 -} is: (Atomic number of Ni = 28)The hybridization involved in complex [Ni (CN) _ 4 ] ^ 2 - is: (Atomic number of Ni = 28)The hybridization involved in complex [Ni (CN) _ 4 ] ^ 2 - is: (Atomic number of Ni = 28)

Options

  1. Adsp2ds{p}^{2}
  2. Bsp3s{p}^{3}
  3. Cd2sp2{d}^{2}s{p}^{2}
  4. Dd2sp3{d}^{2}s{p}^{3}

Correct answer

A. dsp2ds{p}^{2}

Step-by-step solution

[Ni(CN)4]2−{\left[Ni{\left(CN\right)}_{4}\right]}^{2 -}

Oxidation state of Ni is +2

x−4=2x - 4 = 2

x=+2x = + 2

Now, Ni2+=[Ar]3d84s°{Ni}^{2 +} = [ Ar ] 3{d}^{8}4s °

The hybridization involved in complex [Ni (CN) _ 4 ] ^ 2 - is: (Atomic number of Ni = 28)

therefore, CN−{CN}^{-} is a strong field ligand. Hence, all unpaired electrons are paired up.

The hybridization involved in complex [Ni (CN) _ 4 ] ^ 2 - is: (Atomic number of Ni = 28)

therefore, hybridisation of [Ni(CN)4]2−{\left[Ni ( CN{)}_{4}\right]}^{2 -} is dsp2{dsp}^{2}
