Final answer:
The VSEPR model is crucial in predicting the molecular geometry and arrangement of atoms, which are key factors in determining the polarity of a molecule. So, the correct option is C.
Step-by-step explanation:
The importance of considering the Valence Shell Electron Pair Repulsion (VSEPR) model of an atom when determining the polarity of a molecule lies in its ability to predict the molecular geometry and the arrangement of atoms in a molecule. This model considers electron pairs around the central atom to determine the shape of the molecule, which in turn affects molecular polarity. The correct option in the multiple-choice question provided would be c) Because it predicts the molecular geometry and the arrangement of atoms in a molecule. When atoms in a molecule are arranged asymmetrically and there is an uneven distribution of electron density, the molecule can have polar characteristics. The VSEPR model helps to identify areas of electron density and lone pairs, thereby explaining why molecules have certain shapes and the resulting polarity from these shapes. Keep in mind that while the VSEPR model helps in predicting shapes and the theoretical arrangement of atoms, it does not provide information about bond lengths or the presence of multiple bonds.
