Unlock.HCN has a hydrogen atom single-bonded to a carbon atom, and that carbon atom is triple-bonded to a nitrogen atom. These are all non-metals, so the bonds are covalent and HCN is therefore a covalent (aka Molecular) structure. Carbon brings four valence electrons with it; it needs four more to complete its valence shell.Step 1: Counting Valence Electrons. Before we can start drawing the Lewis structure, we need to determine the total number of valence electrons in HCN. This is crucial because valence electrons are the ones involved in chemical bonding. HCN consists of three atoms: hydrogen (H), carbon (C), and nitrogen (N).

Carbon is the central atom, so we can draw the skeletal structure: There is a total of 1 + 4 + 5 = 10 valence electrons, and we use four of them to make the bonds. The remaining 6 go on the nitrogen as lone pairs: Because the carbon lacks an octet, we use two lone pairs from the nitrogen to make two additional bonds: In HCN, six electrons placed on N; 4. Place all remainin Carbon shares three valence electrons of Nitrogen and an extra valence electron to complete its octet. As the Carbon atom accepts the extra valence electron, it attains a negative charge. Hence in CN-, there is a formation of triple bonds between Carbon and Nitrogen atoms.
