This organic chemistry video tutorial shows you how to tell if a compound is aromatic, antiaromatic or nonaromatic by using huckel's rule / number of 4n+2 pi electrons, and features of the compound such as whether or not if it's cyclic, conjugated, sp2 hybridized and planar.
Examples and practice problems in this video include cyclobutadiene, benzene, cyclooctatetraene, pentalene, 1,3,5-hexatriene, naphthalene, anthracene, tropylium ion, cyclopropenyl cation radical & anion, cyclopentadienyl radical cation & anion, cyclooctarienyl dianion, cyclohexatrienyl cation, radical, & anion, pyrrole, furan, pyran, isoxazole, tub conformation of cyclooctatetraene, heterocycles such as thiophene, 1,3-thiazole, pyrimidine, purine, pyrylium ion, & imidazole.
This video also helps you to see which nitrogen atom is basic and which is not. It clearly helps you to see the difference in aromaticity vs antiaromaticity.
