C-Atoms, labeled

The alkyl halide has two different p C atoms (labeled Pi and P2), so two different alkenes are possible one formed by removal of HCI across the a and Pi carbons, and one formed by removal of HCI across the a and P2 carbons. Using the Zaitsev rule, the major product should be A, because it has the more substituted double bond.

A second eccentricity is that atom labels are drawn smaller when in rings. Additionally, whereas it is customary to omit the C atom label for carbon atoms, DEPICT provides them everywhere except in aromatic rings. Aromatic atoms, in turn, are written in lowercase, betraying a kinship to SMILES notation. These peculiarities detract somewhat from the diagram s aesthetic appearance however, they probably reflect the defaults used to visualize SMILES. Reportedly, the defaults can be replaced by adjustable parameters within the Daylight Toolkit.
