RossThe VSEPR (Valence Shell Electron Pair Repulsion) model is mainly used to predict the geometry of molecules based on the arrangement of electron pairs around the central atom. It helps to understand the spatial arrangement of atoms in a molecule and predict the bond angles between them.

What model is used to determine molecular shape?
The VSEPR (Valence Shell Electron Pair Repulsion) model is commonly used to determine molecular shape. This model is based on the idea that electron pairs in the valence shell of an atom repel each other and thus orient themselves in a way that minimizes repulsion to give the molecule its shape.
Can the VSEPR theory be used to predict the shapes of all molecule?
no, not all molecules obey the VSEPR theory, there is an exeption considered for the SIO2 molecules which obeys not the VSEPR theory
What is the molecular geometry of CHCl3 according to VSEPR theory?
The molecular geometry of CHCl3, according to VSEPR theory, is tetrahedral.
What is the molecular geometry of SO2 according to the VSEPR theory?
The molecular geometry of SO2 according to the VSEPR theory is bent.
What is the difference between the Lewis model and the valence-shell electron pair repulsion model?
The Lewis model focuses on the bonding and non-bonding electron pairs around an atom to predict molecular structure and bonding, using Lewis structures. The valence-shell electron pair repulsion (VSEPR) model takes into account the arrangement of electron pairs around a central atom to predict the shape of a molecule, based on the principle that electron pairs repel each other and will arrange themselves to minimize repulsion.
