(a)
Interpretation:
The given reactions are final steps in one industrial synthesis of vitamin A acetate.
The mechanism has to be proposed for the acid-catalyzed cyclization in step-1.
Concept Introduction:
The ring cyclization occurs when an acyclic molecule reacts with acid. by the abstraction of proton from the acid molecule, internal bond shifting occurs to form the cyclization product.
