Can you give the chemical formulas to these structural formulas?
The Common name and chemical formula will appear. Answer options in the first caveat.
For the thumbnail for example you could be answered with C6H2(NO2)3CH3 (chemical formula), C7H5N3O6 (sum of the involved atoms), 2,4,6-trinitrotoluene (IUPAC name), Trinitrotoluene (common name) or TNT (acronym).
When all atoms are labelled, you can't use the second options.
