Which formula represents boron trifluoride?

The formula BF3 accurately represents boron trifluoride, a well-known compound composed of one boron atom and three fluorine atoms. The naming of this compound follows the conventions of chemical nomenclature, where the prefix "tri-" denotes the presence of three fluorine atoms bonded to the boron atom.

Boron has a coordination number of three in this compound, meaning it forms three bonds with neighboring fluorine atoms. In BF3, boron does not follow the octet rule, as it only has six electrons in its valence shell because it is an exception to the rule. The highly electronegative fluorine atoms each contribute one electron to form three single covalent bonds with boron.

The other options listed do not represent boron trifluoride. B2F6 indicates a compound with two boron atoms and six fluorine atoms, which is a different structure entirely, known as diboron hexafluoride. BCl3 is an entirely different compound featuring chlorine instead of fluorine. B3F2 suggests a formula that does not correspond to any known stable compound involving boron and fluorine in boron trifluoride form. Thus, BF3 is indeed the correct chemical formula for boron triflu
