For more detailed information, you must also check out the article written on BF3 Lewis Structure, Molecular Geometry, and Hybridization. a) F2 nonpolar. BF3 Lewis Structure, Molecular Geometry, and Hybridization, https://www.epa.gov/chemical-data-reporting, PCl5 Lewis Structure, Molecular Geometry, Hybridization, and MO Diagram, BCl3 Lewis Structure, Molecular Geometry, and Hybridization, PH3 Lewis Structure, Molecular Geometry, and Hybridization, Nitration and Sulfonation of aromatic compounds (Source: Brotherton RJ et al; Ullmann’s Encyclopedia of Industrial Chemistry 7th ed. The polarity of a molecule is very much dependent on its structure and geometry. b) NO2 polar. (b) If you react BF3to make the ion BF32-, is this ion planar?
