Which of the following molecules has both an electron group geometry and a molecular geometry described as trigonal planar? A)SiH₄ B)PF₃ C)OF₂ D)CHF₃ E)BF₃

Question

Quizplus · Accepted Answer

The electron group geometry for BF3 is trigonal planar, because there are three electron groups (three bonds) surrounding the central boron atom, and they are positioned as far apart as possible in a two-dimensional plane. The molecular geometry is also trigonal planar, because there are no lone pairs on the central atom. Therefore, the correct answer is E, BF₃.
