  • question_answer
    Among the following compounds the one that is polar and has central atom with \[s{{p}^{2}}-\]hybridization is                                                                 [MP PMT 2004; IIT 1997]

    A)                 \[{{H}_{2}}C{{O}_{3}}\] 

    B)                 \[B{{F}_{3}}\]

    C)                 \[Si{{F}_{4}}\]   

    D)                 \[HCl{{O}_{2}}\]

    Correct Answer: A

    Solution :

                    In \[{{H}_{2}}C{{O}_{3}}\] and \[B{{F}_{3}}\] central atom are in \[s{{p}^{2}}\]hybridization but in \[{{H}_{2}}C{{O}_{3}}\] due to the ionic character of \[O-H\]bond it will be polar (High electronegativity of oxygen).
