The following video shows how to write the Lewis structure of hydrocyanic acid, HCN.

  • Get the valence electrons 4+5+1=10
  • draw the skeleton of the molecule
  • Assign lone electrons to terminal atoms completing their octet
  • Give lone pairs to linkers to complete the octet of the central atom.
  • Assign formal charges to see that the structure drawn is the most probable.
