Rank the following from most to least stable.

Question

Quizplus · Accepted Answer

The stability of a molecule is primarily determined by its electronic configuration, with more stable molecules having a lower energy state. In this case, TB3185_00 is a highly stable compound as it is the reference molecule and has a neutral charge. Of the remaining molecules, B is more stable than A and C due to the presence of the aromatic benzene ring, which imparts additional stability through delocalization of electrons. Between A and C, C is more stable as it contains two aromatic rings, while A has only one, making it slightly less stable. Therefore, the correct ranking from most to least stable is TB3185_00 > B > C > A. The only choice that reflects this ranking is choice C.
