WebDifferent compounds with the same molecular formula but different chemical structures are called isomers. Since (in principle at least), different chemical structures have different properties such as melting point or boiling point, then they can be separated from each other. Resonance structures are not a type of isomer. WebAll Isomers: Search Clear form. Search Hits Limit: Filter Single/Multi-component.

Naming stereoisomers. Chemists need a convenient way to distinguish one stereoisomer from another. The Cahn-Ingold-Prelog system is a set of rules that allows us to unambiguously define the stereochemical configuration of any stereocenter, using the designations ‘ R ’ (from the Latin rectus, meaning right-handed) or ‘ S ’ (from the ... pittcmaa
