Isosteres are substances with similar molecular and electronic characteristics. They may not be structurally related, but they often have similar physical properties. They are chemical substances, atoms or substituents that possess nearly equal or similar molecular shape and volume, approximately the same distribution of electrons and which exhibit similar chemical properties. Benzene and pyridine are classical … Continue reading Isosteres
