    Which of the following complexes are not correctly matched with hybridization of their central metal ion? 1. \[[Ni{{(CO)}_{4}}]\]                    \[s{{p}^{3}}\] 2. \[{{[Ni{{(CN)}_{4}}]}^{2-}}\]                   \[s{{p}^{3}}\] 3. \[{{[Co{{F}_{6}}]}^{3-}}\]                         \[{{d}^{2}}s{{p}^{3}}\] 4. \[{{[Fe{{(CN)}_{6}}]}^{3-}}\]                   \[s{{p}^{3}}{{d}^{2}}\] Select the correct answer using the codes given below:

    A) 1 and 2

    B)                                        1 and 3

    C) 2 and 4                 

    D)        1, 3 and 4

    E) 2, 3 and 4

    Correct Answer: E

    Solution :

    Complex                              Hybridization \[[Ni{{(CO)}_{4}}]\]         -              \[s{{p}^{3}}\] \[{{[Ni{{(CN)}_{4}}]}^{2-}}\]        -              \[ds{{p}^{2}}\] \[{{[Co{{F}_{6}}]}^{3-}}\]              -              \[s{{p}^{3}}{{d}^{2}}\]   \[{{[Fe{{(CN)}_{6}}]}^{3-}}\]       -              \[{{d}^{2}}s{{p}^{3}}\]
