I disagree with this. Say tetrachloride to a chemist and ask him what is means. Now say narfs word.

I'd have to disagree with this. A good chemist would be able to break it down bit by bit and tell you what it means (what atoms are bonded to which, and how). After writing it all down, of course.

I'm pretty sure all the names of compounds are words. If something like 'methanal' is a word, why not 'methylaminoethane'? If you follow that rule, then that longass name in the first post is also a word.
