Step 1: Determine the electronic geometry of BF$_1$ using the Valence Shell Electron Pair Repulsion (VSEPR) theory.
The central atom, boron (B), in BF$_3$ has 3 valence electrons and each fluorine atom (F) contributes 1 valence electron, resulting in a total of 4 electron pairs around the central atom.
According to VSEPR theory, these electron pairs will arrange themselves in such a way as to minimize repulsion between them.
Step 2: Determine the arrangement of electron pairs.
Since there are 4 electron pairs, they will arrange themselves in a tetrahedral shape. However, one of these positions is occupied by a lone pair of electrons on the boron atom, which does not participate in bonding.
Final Answer
The electronic geometry of BF$_1$ is tetrahedral due to the presence of 4 electron pairs around the central boron atom, and the molecular geometry is trigonal planar due to the arrangement of 3 fluorine atoms around the central boron atom.
