Dear Stan, I would not insert an 'organic realm' in the hierarchy: it is part of the chemical realm, but it is broader than expected. The rules of Organic Chemistry are not universal as the theorems of mathematics are: many exceptions exist, at least due to the existence of multifunctional compounds. Even increasing the length of an alkyl chain can give surprising results. It is why patents covering syntheses of an infinite number of compounds should never have been accepted, although they were. At the occasion of a course, we learned the main rules needed to face to the realm of Organic Chemistry, but the complexity of structural formulas we face (often natural products) is incredibly vast, and each year we discover more. In parallel, Organic Chemists establish new syntheses and reactions, and the catalog of rules we have is now too large to be likely known by only one Organic Chemist. But compared to Biology, even Organic Chemistry remains "simple" !! It means that we are as the midge trying to understand a computer: it is unlikely that we will be successful. But the challenge is so exciting, and we can take benefits from any increase of knowledge. Best, Michel.
