impossible molecules #773

Closed cryos closed 8 years ago

cryos commented 10 years ago

Dear sirs, thank you for this program to visualize organic molecules for classes. But: It is possible to build "impossible" molecules! Like: a 5 membered ring of Nitrogens with triple bonds between each atom, something like "propidiine" with carbon with 6 valences..

What's wrong with that? Many people may wish to explore strange chemistry, not just stable chemistry. Various computational packages show that these structures are of course, very high in energy. But we do not wish to limit imagination.

While several people have suggested some level of warnings for unusual molecules, we will continue to allow such molecules to be built and explored.
