Polar "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Summary Bond polarity and ionic character increase with an increasing difference in electronegativity. Hence CN has a net dipole moment. It introduces Pauling's electronegativity scale, … May 23, 2025 · Acetonitrile also called cyanomethane or methyl cyanide is a chemical compound with the molecular formula CH3CN. For a molecule, the overall dipole moment is determined by both the individual bond moments and how these dipoles are arranged in the molecular structure. Consequently, nitriles tend to have higher boiling points than molecules with a similar size. The C-N bond is a polar bond since nitrogen is more electronegative than carbon. There aren't enough valence electrons available for each atom to obtain an octet without sharing more than one pair. Ions, like CN- are sometimes confusing because the behave like polar compounds. The presence of an electronegative nitrogen causes nitriles to be very polar molecules.
