Aromaticity
(وهي عكس Electronegativity)
Benzene > Pyridine > Thiophen > Pyrrole > Furan

Electronegativity
Furan > Pyrrole > Thiophen > Pyridine > Benzene

Reactivity toward :-
Electrophilic substitution /
Pyrrole > Furan > Thiophene > Benzene > Pyridine
Nucleophilic substitution /
Pyridine > Benzene

Basicity :
Piperidine > Pyrrolidine > Imidazole > Pyridine > Pyrrole > furan > thiophene > Benzene

Boiling point :
Pyrrole > Pyridine > Piperidine > Pyrrolidine > Thiophen > Benzene > Furan

Piperidine Kb = 2 * 10¯³

pyrrolidine Kb = 10¯³

aliphatic amines Kb = 10¯⁴

Pyridine Kb = 2.3 × 10¯⁹

Pyrrole kb = 2.5 × 10¯¹⁴
