  •  Locations on M.chain +S.chain c count (prefix)
  • M.chain c count (prefix) + bond location & identifier
  • S.chains w/ same count: location1,location2-numberprefix+countprefixS.chains w/ different count:location-prefix(-location-prefix)
  • Locations separated by a comma & followed by a hyphen and number of chains (prefix) + chain count (prefix). 
  • Location, hyphen, chain count (prefix)
  • AlkenesAt least 1 double bond = Unsaturated.Shape at d.bonds: Trigonal planarPrefix: -ene
  • AlkynesAt least 1 triple bond = Unsaturated.Shape at t.bonds: LinearPrefix: -yne
