Aromaticity: A compound is said to be aromatic if it follows the following conditions:
1. The molecule is cyclic.
2. The molecule is planar.
3. The molecule is fully conjugated.
4. The molecule has 4n + 2 electrons (where n = 0, 1, 2, 3, 4, 5...).
Let us study aromaticity by an example:
Question/example to solve:
