Which of the following complexes are not correctly matched with the hybridisation of their central metal ion?
(i) `[Ni(CO)_4], sp^3` (ii) `[Ni(CN)_4]^(2-), sp^3` (iii) `[CoF_6]^(3-) , d^2 sp^3`
(iv) `[Fe(CN)_6]^(3-), sp^3 d^2`
Select the correct answer using the codes given below:

Options

A. 1 and 2
B. 1 and 3
C. 2 and 4
D. 2, 3 and 4

Answer

D

Explanation

`{:("Complex","", "Hybridization"), ([Ni(CO)_(4)], -, sp^(3)), ([Ni(CN)_(4)]^(2-), -, dsp^(2)), ([CoF_(6)]^(3-), -, sp^(3)d^(2)), ([Fe(CN)_(6)]^(3-), -, d^(2)sp^(3)):}`
