The mechanism for the rearrangement reaction of cyclohexa − 1 , 4 − diene into cyclohexa − 1 , 3 − diene in the presence of an acidic solution along with the reason of energetically favourable reaction. Interpretation: The mechanism for the rearrangement reaction of cyclohexa − 1 , 4 − diene into cyclohexa − 1 , 3 − diene in the presence of an acidic solution is to be proposed and the reason corresponds to the statement that is why the reaction is energetically favourable to be explained. Concept introduction: Tautomerization is the process in which molecular formula of compounds remain same but connectivity of atoms or substituents in compounds become different. The stability of compound is the major factor that determines the formation of a compound. The compounds that have low energy are energetically favourable. Conjugated systems possess alternate single and double bonds that results in lower energy of molecule and increase in stability of a molecule.
