Problem: Consider the molecule BF3.What valence orbitals, if any, remain unhybridized on the B atom in BF3?

FREE Expert Solution

We’re asked to determine and identify what valence orbitals remain unhybridized on the B atom in BF3.


We will need to identify the hybrid orbitals used by boron (B) or the hybridization of B in BF3. First, we will have to draw the Lewis Structure of BF3.


Step 1: Determine the central atom in this molecule.

B (EN = 2)  → less electronegative atom than F (EN = 4) → B is the central atom


Step 2: Calculate the total number of valence electrons present.
