Short And Simple Way To Understand Huckel's Rule (AROMATICITY)

A planar molecule having complete delocalisation of (4n+2) pi electron is termed as aromatic hydrocarbon (where n is any integer).

Examples  :-


                                           






                                              CONDITIONS FOR AROMATICITY  
  • For the molecule to be aromatic it should possess a single cyclic cloud of delocalised    electron that lies above and below the plane of the molecule.
  • The molecule should be planar.
  • The molecule should contain (4n+2) pi  electrons.
  • The molecules which do not satisfy any of the above condition are said to be non-aromatic
