  • question_answer
    The correct order of hybridization of the central atom in the following species \[N{{H}_{3}}\] \[{{[PtC{{l}_{4}}]}^{2-}},\,PC{{l}_{5}}\] and \[BC{{l}_{3}}\] is [IIT Screening 2001; BHU 2005]

    A)                 \[ds{{p}^{2}},\,\,ds{{p}^{3}},\,\,s{{p}^{2}}\]and \[s{{p}^{3}}\]

    B)                 \[s{{p}^{3}},\,\,ds{{p}^{2}},\,\,ds{{p}^{3}},\,\,s{{p}^{2}}\]

    C)                 \[ds{{p}^{2}},\,\,s{{p}^{2}},\,\,s{{p}^{3}},\,\,ds{{p}^{3}}\]            

    D)                 \[ds{{p}^{2}},\,\,s{{p}^{3}},\,\,s{{p}^{2}},\,\,ds{{p}^{3}}\]

    Correct Answer: B

    Solution :

                    Hybridization of N in \[N{{H}_{3}}\] is \[s{{p}^{3}}\] that of Pt in \[{{[PtC{{l}_{4}}]}^{2-}}\] is \[ds{{p}^{2}}\] that P in \[PC{{l}_{5}}\] is \[s{{p}^{3}}d\] and that of B in \[BC{{l}_{3}}\] is \[s{{p}^{2}}\].
