Higher polarity means

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 … Ver mais 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, … Ver mais 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 … Ver mais • Chemistry portal • Chemical properties • Colloid • Detergent • Electronegativities of the elements (data page) Ver mais While the molecules can be described as "polar covalent", "nonpolar covalent", or "ionic", this is often a relative term, with one molecule simply … Ver mais Contrary to popular misconception, the electrical deflection of a stream of water from a charged object is not based on polarity.
