In a strongly acidic solution, cyclohexa-1,4-diene tautomerizes to cyclohexa-1,3-diene. Propose a mechanism for this rearrangement, and explain why it is energetically favorable.
Here we have show the mechanism for the interconversion of cyclohexa-1,4-diene to cyclohexa-1,3-diene.
Here H-A represents the general form of acid and A- is its conjugate base. In this reaction
Cyclohexa-1,4-diene can be converted into cyclohexa-1,3-diene in presence of an acid and forms carbocation which on further reaction in presence...
