First molecule | Comment 5 of 8 |
I wonder why the original contest did not include the initial building block, methane, CH4.

When Ady first proposed this I saw some spellings which were incompatible with my High School Chemistry studies.  One term referred to a medicinal drug rather than a molecule.

Somehow I stumbled upon what was possibly Ady's source:, there I saw the spellings which he had offered.

At the time when I questioned the spellings offered "propine" was the only one which Google addressed.  Today I find that those with the "-yne" do appear under Google search with an "-ine" ending.  I'll not attempt what is the accepted Anglo-American spelling but it does seem that in some places alternates are acceptable.

Just for interest.
