26.28The double bond has a tendency to become conjugated with the carbonyl group. Two mechanismsare more likely than any others under conditions of acid catalysis. One of these involves protonationof the double bond followed by loss of a proton from C-4.The other mechanism proceeds by enolization followed by proton-induced double-bond migration.26.29See the June, 1995, issue of the Journal of Chemical Education,pages 541–542, for the solution tothis problem.26.30Solutions to molecular modeling exercises are not provided in this Study Guide and Solutions Man-ual.
