The geometry of the BF ₃ molecule is called trigonal planar (see Figure 5). The fluorine atoms are positioned at the vertices of an equilateral triangle. The F-B-F angle is 120° and all four atoms lie in the same plane.The geometry of the BF ₃ molecule is called trigonal planartrigonal planarTrigonal planar: triangular and in one plane, with bond angles of 120°. Trigonal bipyramidal: five atoms around the central atom; three in a plane with bond angles of 120° and two on opposite ends of the molecule. › molecular-geometry

(see Figure 5). The fluorine atoms are positioned at the vertices of an equilateral triangle. The F-B-F angle is 120° and all four atoms lie in the same plane.

Why is BF3 trigonal planar?

As we know VSEPR theory is used to predict the shape of compounds. According to this theory a compound will have trigonal planar geometry if it contains 3 bond pair and 0 lone pair. Structure of BF3contains 3 bond pair and 0 lone pair. This means it will have trigonal planar geometry.
