    The number of lone pairs of electrons present on the central atom of \[{{\operatorname{CIF}}_{3}}\]is:

    A) O                     

    B) 1       

    C) 2                                 

    D) 3

    Correct Answer: C

    Solution :

    \[\operatorname{Cl} \left( ground state \right)\] \[=3{{s}^{2}}3{{p}^{2}}\times 3{{p}^{2}}y3{{p}^{l}}z\] \[\operatorname{Cl} \left( excited state \right)\]            \[\] \[=3{{s}^{2}}3{{p}^{2}}x3{{p}^{2}}z3{{p}^{l}}z=3{{d}^{l}}\] It is \[{{\operatorname{sp}}^{3}}d\]hybridized (trigonal bipyramidal structure) It has T-shape with two lone pairs.
