I just bought a molecular modeling kit for my toddler ("Snatoms").
To use the kit to play with her, I want to start out by memorizing a list of all molecules (isomers) fitting these criteria:
- only contains C, H, and/or O
- contains a maximum of 6 atoms
I started out by noodling around with Lewis diagrams and wikipedia... but then I ran into the various isomers of C2H2O2:
I wanted to do this search on a chemical database (like chemspider.com) but I couldn't find a criterion that would filter the search by number of atoms in the molecule (isomer).
Is there a name for this "number"?
