In chemistry, polarity refers back to the separation of electrical cost inside a molecule or chemical compound, leading to a web optimistic or damaging cost on both finish of the molecule. Molecules are categorised as polar, nonpolar, or ionic primarily based on their polarity and the varieties of chemical bonds they include.
Polar molecules have a everlasting dipole second, which means that they’ve a separation of optimistic and damaging fees. 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).
