What is the F-B-F bond angle in BF₃? A)less than 109.5° B)109.5° C)120° D)greater than 120°

Question

Quizplus · Accepted Answer

In BF₃, the central atom (B) is surrounded by two fluorine atoms (F) and two sulfur atoms (S) along with one unit of unshared electron pair (U) and one bridging atom (B). The molecular geometry of this compound is trigonal bipyramidal, with three equatorial positions and two axial positions. The F-B-F bond angle in the trigonal bipyramidal geometry is 120°, as the three equatorial positions are equivalent and form a perfect trigonal planar arrangement. Therefore, the answer is option C, 120°.
