Note that nonsensical structures can be drawn with this package
for example the structure headed \naphdrv[ob]
has a pentavalent carbon atom ... even first year students shouldn't be making

If you want proper chemical structures do not use LaTeX packages; all
the ones that I have seen do not have sufficient intelligence and the
requisite power to do chemical structures properly, and, they are
very hard to use.
