    Which is a planar molecule?

    A) \[PC{{l}_{3}}\]                                  

    B) \[BC{{l}_{3}}\]

    C) \[N{{H}_{3}}\]                                  

    D) \[{{H}_{3}}{{O}^{+}}\]

    Correct Answer: B

    Solution :

    \[BC{{l}_{3}}\]is \[s{{p}^{2}}\]hybridised with planar trigonal structure\[{{H}_{3}}{{O}^{+}},N{{H}_{3}}\]and\[PC{{l}_{5}}\]are \[s{{p}^{3}}\]hybridised with  pyramidal structure.
