In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms. … 展开
Not all atoms attract electrons with the same force. The amount of "pull" an atom exerts on its electrons is called its electronegativity. Atoms with high electronegativities – such as fluorine, oxygen, and 展开
Contrary to popular misconception, the electrical deflection of a stream of water from a charged object is not based on polarity. The deflection … 展开
A molecule is composed of one or more chemical bonds between molecular orbitals of different atoms. A molecule may be polar either as a result … 展开
Determining the point group is a useful way to predict polarity of a molecule. In general, a molecule will not possess dipole moment if the individual bond dipole moments of the molecule … 展开

Solvent - Wikipedia
The solvents are grouped into nonpolar, polar aprotic, and polar protic solvents, with each group ordered by increasing polarity. The properties of solvents which exceed those of water are bolded.
The ACS Green Chemistry Institute maintains a tool for the selection of solvents based on a principal component analysis of solvent properties.

Polar and Nonpolar Molecules - Science Notes and Projects
在sciencenotes.org上查看更多信息Understanding and identifying polar and nonpolar chemical bondsmakes it easier to understand polar molecules. In a polar bond, one atom has a partial positive electrical charge, while the other atom has a partial negative electrical charge. In other words, a polar bond forms an electric dipole. In a nonpolar bond, atoms sha…Nonpolar Molecule Definition and Examples - ThoughtCo
2019年7月3日 · A nonpolar molecule has no separation of charge, so no positive or negative poles are formed. In other words, the electrical charges of nonpolar molecules are evenly distributed across the molecule. Nonpolar molecules …
