La teoría describe el tipo de geometría atendiendo a los pares de electrones de la capa más externa del átomo central en un compuesto determinado. Square pyramidal. a. The Model (VSEPR) Examples. Ejemplo: El Fluoruro de hidrógeno o ácido fluorhídrico (HF). X represents an atom bonded to the central atom, and E represents the lone pair (s According to the VSEPR theory, in a molecule with the general formula AX2E2, the molecule's structure would feature four regions of electron density around the central atom (A).
