Boron trifluoride - Wikipedia
WEBThe geometry of a molecule of BF 3 is trigonal planar.Its D 3h symmetry conforms with the prediction of VSEPR theory.The molecule has no dipole moment by virtue of its high symmetry. The molecule is isoelectronic with the carbonate anion, CO 2− 3.. BF 3 is commonly referred to as "electron deficient," a description that is reinforced by its exothermic reactivity toward Lewis bases.
