Question

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). be planar unless structure obviously prevents planarity. If there is more than one conjugated ring, count electrons in the largest.) 1. A.Electrons in a cyclic conjugated system. B.The compound is (a, aa, or na) 2. A.Electrons in a cyclic conjugated system B.The compound is (a, aa, or na Submit Answer Retry Entire Group 2 more group attempts remaining

Explanation / Answer

1 A. Electrons in a cyclic conjugated system 4.

B. The compound is anti aromatic (4 pi electron sysyem. Therefore anti aromatic).

2. A. Electrons in a cyclic conjugated system 6.

The compound is non aromatic (In the ring one sp3 carbon is present. Therefore non aromatic)
