Name the following cycloalkenes using systematic names Map Name the following cycloalkenes using systematic names. Jasperse note: you don't need to deal with whether substituents on the rings are R/S or cis/trans in this problem, since 3-D stereochemistry is not illustrated. No EIZ stereo needs to be designated for cycloalkenes. Notes: make sure the alkene carbons are #'s 1 and 2, and if one but not both alkene carbons are substituted, make the substituted one #1 and the CH carbon...
