(In reply to First molecule by brianjn)

Br,
The source was Russian  Linguisting  Oympiade, which Tanya mentions in her blog. The word they've used was "elements', I  wrote "entities " and  you suggested "molecules" which seemed appropriate and I accepted your choice.
Looking up your link one can find a thread, including full solution and -yne vs -ine   debate.
Quoting BN: Just for interest.
