Question

For each of the species below, identify any cyclic conjugated system, then: Determine the number of electrons in a system of cyclic conjugation (zero if no cyclic conjugation). 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.) Electrons in a cyclic conjugated system. The compound is (a, aa, or na) Electrons in a cyclic conjugated system. The compound is (a, aa, or na)

Explanation / Answer

1.

A.6 electrons

B.a, odd no.of electron pairs in the ring

2.

A.8 electrons

B.aa, even no.of electron pairs in the ring
