The bond angles in antimony trifluoride are 87°. Describe the bonding in SbF3, including a picture of the orbital overlap interaction that
creates the Sb-F bonds.
✓orbitals from the inner atom. An outer halogen atom always uses one of
✓valence orbitals, and fluorine has n = vvalence orbitals,
Bond angles near 90° signal interactions of valence
its valence
✓orbitals to form a bond. Antimony has n =
so each of the three bonds in SbF3 can be described as resulting from overlap between a
orbital from F. There are three
vorbital from Sb and a
bonds that point at near-right angles to one another.
