D) 2n
E) 3n

Question

Quizplus · Accepted Answer

The F1F1F1S1F1F1F10 notation represents a fully delocalized pi electron system in an aromatic compound. According to Huckel's Rule, an aromatic compound must have a pi electron system containing 4n + 2 electrons, where n is a nonnegative integer. This means that the number of F1F1F1S1F1F1F10 electrons present in an aromatic compound must be of the form 4n + 2 in order for the compound to be aromatic. Therefore, choice A is the correct answer.
