Primarily because I dont want to ask a bunch of multiple choice questions.

So in some respects, Im admittedly reinventing the wheel here.

But many of the structures have IUPAC names which can be rather large andor outside of the scope of IUPAC nomenclature my students learn.

Chem Draw Onliner License Does Not

And our ChemDraw license does not include the structure-to-name feature.

SMILES is a condensed version of the structure, almost human readable, and ChemDraw can copy a structure directly in SMILES format.

I coded the correct SMILES into the grader as well as some of the common errors for feedback purposes and released it to my students.

All they had to do was follow along bond for bond with my tutorial video and get the correct answer.

When I checked their.jpg structures, all of the structures appeared to be correct What is going on.

If you start from the left side, you get one SMILES, from the right you get a different SMILES.

I understand that all of these are valid SMILES, but I feel that one structure should give the same SMILES from ChemDraw, regardless of how the molecule happened to be drawn.

Its not human readable, but at least the same structure seems to give the same InChI Key regardless of how the structure is drawn.

Chem Draw Onliner Software Can Interpret

If anyone has any suggestions, let me know It needs to be something unambiguous that the students can use and the non-chemistry quiz grading software can interpret the answer.
