We are asked to sort the following compounds as either containing aromatic rings or cycloalkane/cycloalkene rings.
4 Rules of aromaticity:
2. Fully conjugated?
4. Huckel's Rule(4n + 2) number of π electrons
When the 4 rules are met, we can conclude that the molecule is aromatic.
For each structure below, determine the number of π electrons. Indicate whether the structure is aromatic, nonaromatic, or antiaromatic. Assume planarity.
