- 14. Which of the following compounds is non-aromatic?Question 15 In the blank for each molecule, enter A, B or C according to the code below: A-aromatic if planar B anti-aromatic if planar C-non-aromatic (does not matter if it is planar or not because other conditions for aromaticity or anti- aromaticity are not met) For those with more than one ring, consider the molecule as a WHOLE, rather than as separate rings. So if all of the rings together don't make for an aromatic molecule, then choose B or C.
