A: What should be the nomenclature of this organic compound?

orthocresolAlthough this isn't disputed by anybody here, let's start by noting that in general, suffixes have greater "priority" over double and triple bonds in numbering. The rules are given in Nomenclature of Organic Chemistry: IUPAC Recommendations and Preferred Names 2013 (Blue Book): P-14.4 When sever...

@orthocresol I agree, these are the rules as written. However, I am not sure that this is really what is intended for single rings with double bonds.
I don’t find a clear example for or against simple cases like cyclohex-6-ene-1,2,4-triol or cyclohex-(1)6-ene-1,2,4-triol in the Blue Book.
Every structure drawing program that I have checked names this example as cyclohex-6-ene-1,2,4-triol, which shouldn’t be allowed according to the rule that you have found.
However, the rule P-31.1.4.2 that you have found is for bi- and polycyclic von Baeyer parent hydrides and not for simple monocyclic structures.
The clear example shown in the blue book (4-azabicyclo[8.5 .1 ]hexadec-1 (15)-ene) is such a bicyclic structure.

Hmmmm, interesting.... I’ll have a look again when I can. I must admit sometimes I can’t keep track of which part of the blue book I am in.

Does Oxford have a varsity type website with an RSS feed? @orthocresol
Like this, with the sciences?
Btw, Twitter has a chemistry feed now.
