The VSEPR AX, class (the first member of the AX, family) Example 2: BF, Experimentally it is determined that BF, is a trigonal planar molecule with all B-F bonds identical, and all F-B-F angles equal to 120° (a) Draw the Lewis structure for the BF, molecule Construct a model of the sp' hybrid orbitals, arranging them as shown below: Make a model of BF, by inserting three gray connectors into the set of three holes on a (brown) atom center so that they lie on a plane and are 120° apart. Connect three white balls, representing fluorine atoms, to the three gray connectors inserted in the (brown) atom center. As before, each connector represents a bonding pair of electrons, with one of the electrons in each bond coming from the boron atom and the other coming from a fluorine atom. (b) Now fill in the report table for BF
