The formal replacements of a -CH= group of benzene by -A= and -"s= groups give 6,, non-benzenoid aromatic systems, pyrylium and thiopyrylium cations, respectively. Both the cations are supposed to be resonance hybrids of Kekulg-type structures (A) and carbonium ion structures (B) in the ground stat
