Acid equivalents: 1 (amount of H) Bromine can now use the d-orbitals to hybridise. The BrF3 molecule is polar because the charge distribution between the bromine and three fluorine atoms is not uniform.. In this case, the Because polar molecules have a positive and negative charge ends, the positive charge end of a molecule will attract to the negative end of adjacent molecule with the same or different kind of molecule. B) And so you have these two How many unhybridized p-orbitals? Hybridisation was first introduced by Pauling to explain the equivalent nature of bonds in a molecule.
