"xukmiri", "xukmiro", and "xukmiru"?


I think it'd be better to just cmenenize the compound's name, rather
than re-implementing a nomenclature with inconsistencies and
unnameable molecules..... ha ha, I fool nobody.

**RAMBLING WARNING**
It's been a while since I've taken OC, but I'll give it a shot. tanru
have lots of infrastructure already, so let's use tanru.

Tentative Rules:
* Ought to end with "xukmi", especially if context isn't established,
or if hydrogen atoms have been elided, and they certainly will in
organic chemistry. So, HOH could be written verbosely as "cidro kijno
cidro", or less so with "kijno xukmi".
* Repetition of atoms (or chemical chains) should be indicated using
"[PA mei] <chemical>". So, propane would be "ci mei tabno xukmi".
Methane would be "tabno xukmi"
* To indicate the bond type, use "[PA mei] dikca". Without dikca,
there is a single bond. With dikca, a double bond. For other bonds,
use something different. For example, for ionic bonds, use "dukti".
NaCl would be "sodna dukti kliru"
* Loops would use "clupa {(co'e <bond>) <chemical>}". The beginning of
the chemical is joined with the end, using the "co'e" bond. A ring of
5 carbons would be "clupa mumei tabno xukmi"
* Branches should be joined with "joi". The first item listed is the
one that connects with the previous chemical chain, and connects to
the following chain. Branches that are duplicates could be indicated
using "joi xi PA". For example, methane would be "tabno joi xi vo
cidro", and the hydrogens won't be elided.
* Chirality would be indicated with a direction of twist. I don't know
any words for CW or CC.
* Chair/Boat configuration (are those the correct words?) could be kruca/panra

Let's watch it and myself fail about with some simple examples.

I am not sure the grouping of the tanru is really the way it should be.
