The word "aromatic" through started with benzene and its derivatives only, now it signifies a large variety of organic compounds. To examine the presence of aromaticity, the following tips are useful. Ensure that your compound is cyclic. Each corner of the ring is either a double bonded atom, or must carry a negative charge or a positive charge or a hetero atom planar. You may get deceived while examining this. On the plane of the paper everything appears planar unless specially specified. Your compound should have a closed shell of (4n+2) electrons. When the closed loop contains 4n electrons, the system is rather less stable or antiaromatic.
