Expert Answer:

Huckle rule is used to determine whether a planar ring molecule will have aromatic properties.
A cyclic ring molecule follows Hückel's rule when the number of its π-electrons equals 4n+2 where n is zero or any positive integer.
For example, the benzene molecule, which has 3 π bonds or 6 π electrons, is aromatic
