In chemistry, polarity refers back to the separation of electrical cost inside a molecule or chemical compound, leading to a web optimistic or unfavorable cost on both finish of the molecule. Molecules are categorized as polar, nonpolar, or ionic primarily based on their polarity and the sorts of chemical bonds they comprise.
Polar molecules have a everlasting dipole second, which means that they’ve a separation of optimistic and unfavorable expenses. This happens when the electronegativity of the atoms within the molecule is totally different, inflicting the electrons to be unequally shared. Examples of polar molecules embrace water (H2O) and hydrogen chloride (HCl).
