The PF3 molecule has a dipole moment of 1.03 D, but BF3 has a dipole moment of zero. How can you explain the difference?
CHM 211 Week 2 Notes Valence Bond Theory (1.7) - Molecular Orbital Theory (2.7) 1.7 Valence Bond Theory - Chemical bonds are the result of overlapping atomic orbitals - When two 1S orbitals overlap, a sigma bond is formed - The internuclear axis is an imaginary line between the nucleus of the two orbitals where the electron density is the highest. As you get farther away from this line, density decreases 1.9 Hybridized Atomic Orbitals - To hybridize orbitals means to mix them together, resulting in a combination of the two - If you start with a 2S orbital and 3 2P orbitals, the result is 4 SP3 hybridized orbitals - SP3 hybridization results in a sigma bond - a good example of this is in ethane. The bond between the two carbon atoms is an overlap of 2 SP3 orbital
