Which formula represents boron trifluoride?

Boron trifluoride is represented by the formula BF3. In this compound, boron (B) is the central atom surrounded by three fluorine (F) atoms. The nomenclature reflects the number of each type of atom present in the molecule, which is essential for understanding chemical composition and structure.

In BF3, the subscript '3' indicates that there are three fluorine atoms bonded to one boron atom. This arrangement results in a trigonal planar geometry due to the three fluorine atoms being evenly distributed around the boron atom, which aligns with the valence shell electron repulsion theory.

The other formulas listed do not correspond to boron trifluoride. For instance, B2F6 indicates a different structure where there are two boron atoms and six fluorine atoms, which forms a dimer of BF3. BCl3 refers to boron trichloride, using chlorine instead of fluorine as the halide. Finally, B3F2 suggests a different stoichiometric ratio that is not representative of boron trifluoride. Therefore, BF3 is accurate because it specifically denotes the presence of one boron atom paired with three fluorine atoms, matching the nomenclature of boron trif
