Definitions:

Isomeric

Molecules that have the same molecular formula but differ in the arrangement of their atoms or in the spatial orientation of their atoms.

Boron Trifluoride

A binary compound composed of boron and fluorine with the formula BF3, known for its role as a strong Lewis acid in organic and inorganic chemical reactions.

Hybridized

A concept in chemistry where atomic orbitals mix to form new hybrid orbitals for bonding, providing a more accurate description of molecular bonding and geometry.

FBF Bond Angle

Refers specifically to the bond angle in a molecule of BF3 (Boron Trifluoride), where the three atoms of fluorine are bonded to a central boron atom, typically close to 120 degrees due to the trigonal planar shape.
