Indicate whether each structure is aromatic, nonaromatic, or antiaromatic. Compound A is imidazole, which is a 5 membered ring with two internal alkenes. A N H with lone pair is located between the two alkenes. On the ring two positions away is another nitrogen, which has one lone pair and is s p 2 hybridized. Compound B is two fused benzene rings. Compound C is a 5 membered ring with two internal alkenes. There is a C H 2 group between the two alkenes. Compound D is a 7 membered ring with three internal alkanes and a C H plus flanking two of the alkenes. Compound E is thiazole. which is a 5 membered ring with two internal alkenes. In between the alkenes is a sulfur with two lone pairs. On the ring two positions away is a nitrogen which has one lone pair and is s p 2 hybridized.
