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 (Presume rings to be planar unless structure obviously prevents planarity. If there is more than one conjugated ring in the largest.) A. Electrons in a cyclic conjugated system. 4 B. The compound is (a, aa, or na) na A. Electrons in a cyclic conjugated system. 6 B. The compound is (a, aa, or na) aa

Explanation / Answer

1)

A) Electrons in a cyclic conjugated system are zero.

B) It is non-aromatic due to the absence of cyclic conjugated system and cyclic ring.

2)

A) Electrons in a cyclic conjugated system are four

B) It is anti-aromatic

4n = 4 pi electrons

n = 4/4 = 1 so it is anti-aromatic.
