Brf3是极性还是非极性

BRF3 (Bromine Trifluoride) is a polar molecule due to the presence of a lone pair of electrons on the central bromine atom and its trigonal bipyramidal molecular geometry. The three fluorine atoms are positioned in an equatorial plane, while the two other positions of the axial plane are occupied by a lone pair of electrons and a bromine atom, respectively. The electronegativity difference between bromine and fluorine atoms creates a dipole moment, which gives BRF3 its polarity. In summary, BRF3 is a polar molecule.
