6. Using the given empirical values for enones, calculate the à max value for the given compound. Show all calculations (10pts). Base Values: Six-membered ring or acyclic parent enone Five-membered ring parent cnone Acyclic dienone 202 nm Increments for: Double-bond-extending conjugation Alkyl group or ring residue = 30 nm a-10 nm B = 12 nm y and higher = 18 nm S nm Exocyclic double bond

Answer 1

This DB is common exocyclic for 2 rings so aunted twice according woodward Leser Rules Amax = 1 Gmembered parent chone = 2150 3 double bond extension SX30=gonm aperirilmes et Exocyche DBS = 3x5=45nm. albylos ring descue = L = loum B = 12 nm Yand higher = 5x 18 nm. lomb Amax 432nm
