    Which of the following molecules has trigonal planar geometry?

    A)  \[I{{F}_{3}}\]                                    

    B)  \[PC{{l}_{3}}\]

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

    D)  \[B{{F}_{3}}\]

    Correct Answer: D

    Solution :

                    \[I{{F}_{3}}\] has bent-T shaped geometry. \[PC{{l}_{3}}\]has pyramidal geometry. \[N{{H}_{3}}\] has pyramidal geometry. \[B{{F}_{3}}\]has trigonal planar geometry.
