Write the name of the following compounds by the Hantzsch-Widman system: (a) [Image of a bicyclic compound with two nitrogen atoms and one oxygen atom] (b) [Image of a bicyclic compound containing a benzene ring fused to a six-membered ring with one nitrogen and one oxygen]
Understand the Problem
The question is asking to provide the systematic names of two heterocyclic compounds using the Hantzsch-Widman nomenclature system. This system is a standardized way of naming heterocyclic compounds based on the size of the ring and the heteroatoms present.
Answer
The Hantzsch-Widman names are: (a) 1-Oxa-3,7-diaza-bicyclo[3.3.0]octadiene (b) 3-Oxa-1-aza-bicyclo[4.4.0]decane
The Hantzsch-Widman names for the compounds are: (a) 1-Oxa-3,7-diaza-bicyclo[3.3.0]octadiene (b) 3-Oxa-1-aza-bicyclo[4.4.0]decane
Answer for screen readers
The Hantzsch-Widman names for the compounds are: (a) 1-Oxa-3,7-diaza-bicyclo[3.3.0]octadiene (b) 3-Oxa-1-aza-bicyclo[4.4.0]decane
More Information
The Hantzsch-Widman system is used for naming heterocyclic compounds, providing a systematic way that relies on prefixes and suffixes to indicate the heteroatoms present and the ring size.
Tips
Pay attention to the numbering and the order of citing heteroatoms in the name. Remember to use the correct prefixes for multiple identical heteroatoms.
