Draw the complete Lewis structure of a molecule with the following characteristics (parts a-d), showing all atoms, lone pairs of electrons, and formal charges. Make sure that your assigned formal charges sum to the overall charge on the molecule.
a) A molecule with the formula C2H5N having no formal charge on any atom.
b) A cation of the formula C2H8N+
c) An anion of the formula C2F3O- having a C=O double bond.
d) Two neutral molecules of the formula C2H3N, both having a C=N triple bond (Hint: one has no formal charges, whereas the other has two.)
