Fused and Bridged Bicyclic Nomenclature

Bicyclic rings possess multiple ringed systems within the same molecule

Bridged Bicyclic Nomenclature (Three Rings)

  • The bridgehead atom (one of the circled ones) must always be in the “1” position
  • The name is formatted as bicyclo[ringsize1.ringsize2.ringsize3]alkane

Fused Bicyclic Nomenclature (Two Rings)

*Error: The name of this molecule was misstated in the video. Please refer to the above name (pentane)!

Awesome job! These are some of the hardest molecules to name, so if you got them, you’re ahead of the curve.
