For each of the species below, identify any cyclic conjugated system, then: A. Determine the number of electrons in a system of cyclic conjugation (zero if no cyclic conjugation). B. Specify whether the species is "a"-aromatic, "aa-anti-aromatic, or "na"-non-aromatic (neither aromatic nor anti-aromatic). (Presume rings to be planar unless structure obviously prevents planarity. If there is more than one conjugated ring, count electrons in the largest.) A.Electrons in a cyclic conjugated system. B.The compound is (a, aa, or na) 2. A.Electrons in a cyclic conjugated system.

Aromaticity a. For the molecule below is the ring (as shown - the particular resonance form drawn) aromatic, why or why not? b. Using correct arrow-pushing convention, show the formation of a resonance form of the above structure that is aromatic. What is the charge of the five-membered ring in the main contributing resonance form? C.

is this aromatic？show steps to verify your answer

I keep getting this question wrong but I’m doing everything correctly.

Consider the structure of the cyclopentadienyl anion. cyclopentadienyl anion Complete the Frost circle (i.e., use the inscribed polygon method) for the anion. Classify the aromaticity of the compound. Aromatic Nonaromatic Antiaromatic Energy Answer Bank 1 1.

Option A, B and E have been tried together for aN attempt already. That answer was NOT correct.
