Concept

Problem: For each structure below, determine the number of π electrons. Indicate whether the structure is aromatic, nonaromatic, or antiaromatic. Assume planarity.

FREE Expert Solution

We are asked to sort the following compounds as either containing aromatic rings or cycloalkane/cycloalkene rings.


4 Rules of aromaticity: 

1. Cyclic?

2. Fully conjugated?

3. Planar?

4. Huckel's Rule(4n + 2) number of π electrons

When the 4 rules are met, we can conclude that the molecule is aromatic.
