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 geometry. \[PC{{l}_{3}}\] has pyramidal geometry. \[N{{H}_{3}}\] has pyramidal geometry. \[B{{F}_{3}}\] has trigonal planar geometry.
