Thiazine compounds are commonly used in making dyes, drugs, and insecticides. A 1,2-thiazine is depicted below. Lone pairs, hydrogen atoms, and carbon labels are omitted in this structure (but are still present). a. Which orbitals compose the σ bond between the N and S atoms in the thiazine shown?
b. Which orbitals compose the π bond between the N and C atoms in the thiazine shown?
c. One property of aromatic compounds is that they are flat (planar). Based on this qualifica- tion, could this thiazine be aromatic? Briefly explain.
