H\"uckel's Rule A cyclic, planar, fully conjugated molecule is aromatic (anomalously stable) if and only if it contains 4n + 2 π electrons, where n is a non-negative integer: N_π = 4n + 2 (n = 0, 1, 2, …) cccl n & N_π & Example & Species , 0 & 2 & Cyclopropenyl cation & C_3H_3^+ , 1 & 6 & Benzene & C_6H_6 , 2 & 10 & Naphthalene & C_10H_8 , 3 & 14 & Anthracene & C_14H_10
