Deduce the molecular shape og BF3 on the basis of VSEPR theory.
The central atom , boron(Z= 5, 1s22s22p1) has three valence electrons. In the formation of BF3 molecule, each electron in the valence shell of B-atom forms a bond pair with F-atom. As a result, the central boron atom is surrounded by three bond pairs and the molecule adopts trigonal planar geometry. In this geometry, all the F-B-F bonf angles are 120o. This geometry is planar because the three F-atoms and B-atom lie in the same plane.
