Respuesta :

There are two characteristics of molecules, one is geometry and other is shape. Shape is excluding lone pair surrounding the central element and geometry is including the lone pair. Therefore, the bond angle is less than proper 120°.

What is VSEPR theory?

VSEPR stands for valence shell electron pair repulsions. VSEPR theory is used to predict the shape and geometry of molecules on the basis of valence electrons pairs that are present around the central element of the molecule.

According to VSEPR theory, Lone pair lone pair repulsion is greater than bond pair bond pair repulsion. There are so many limitations of VSEPR theory. There is a repulsion between bond pair electrons and lone pairs present on the central element.

If the molecular geometry were bent and had only one lone pair of electrons, then the bond angle is less than proper 120° angle due to lone pair and bond pair repulsion according to VSEPR theory.

Therefore, the bond angle is less than proper 120°.
