BBZA-010 日本AV ; To determine whether a given molecule is polar or nonpolar, we need to consider the molecular geometry and the electronegativity of the atoms in the molecule. 1. **Electron Geometry and Molecular Geometry**: First, the electron geometry of the molecule (the arrangement of electron pairs around the central atom) determines the molecular geometry (the arrangement of the atoms in the molecule). The molecular geometry then influences the molecule's polarity. 2. **Net Dipole Moment**: A molecule is polar if it has a net dipole moment (the sum of all the polar bonds in the molecule). To have a net dipole moment, the molecule must not be symmetrical in its molecular geometry. If the molecule is symmetrical in its molecular geometry, it will cancel out the dipole moments and the molecule will be nonpolar. 3. **Symmetry**: Therefore, a molecule is polar if it is asymmetrical in its molecular geometry. If a molecule is symmetrical in its molecular, it is nonpolar. The diagram emphasizes the importance of the molecular geometry in determining the polarity of a molecule. The molecule is polar if it has the net dipole moment which is determined by the molecular geometry of the molecule. The links between electronegativity, molecular geometry, and dipole moment of the molecule are highlighted in this diagram. - 免费预告片中文字幕 srt。
