Draw the Lewis structure of HCN. include lone pairs.

Answer:

The Lewis structure of the hydrogen cyanide molecule is represented by the image shown.

What is the Lewis structure?
We know that the Lewis structure is showing us the relationship between the electrons pairs in the compound and its overall properties. The Lewis structure consists of the symbol of the element and the electrons pairs that surround the atom.

We can see that in hydrogen cyanide there is a nitrogen atom and there is a hydrogn atom and also one carbon atom. The bond between carbon and nitrogen is covalent while the bond between hydrogen and the cyanide moiety is covalent.

Final answer:

To draw the Lewis structure of HCN, place H at the center and connect it to C. Add lone pairs around N and C to satisfy the octet rule.

Explanation:

The Lewis structure of HCN can be drawn by following a few steps:

  1. First, determine the total number of valence electrons. H has 1 valence electron, C has 4 valence electrons, and N has 5 valence electrons, giving a total of 10 valence electrons.
  2. Next, place the least electronegative atom, which is H, in the center. Connect the H atom to the C atom using a single bond.
  3. Next, place the remaining valence electrons around the atoms to satisfy the octet rule for all atoms. Put two lone pairs on the N atom and three lone pairs on the C atom.
  4. Lastly, check if all atoms have achieved an octet. If any atom does not have an octet, form double or triple bonds until all atoms have an octet.

The Lewis structure of HCN shows a single bond between C and H, and a triple bond between C and N. The C atom has 3 lone pairs and the N atom has 2 lone pairs.
