The cyanide ion, also known as CN-, is a chemical compound composed of a carbon atom bonded to a nitrogen atom. Two charges are present with a negative charge in the middle (red shade), and a positive charge at the ends (blue shade). Therefore, the only chiral point groups are Cn and Dn. To draw the Lewis dot structure for the cyanide ion (CN⁻), follow these steps: Determine the total number of valence electrons: Carbon has 4 valence electrons, and nitrogen has 5. This is due to the difference in electronegativity between carbon (C) and nitrogen (N).
