(a)

Interpretation Introduction

Interpretation:

The major product should be drawn.

Concept Introduction:

Retrosynthesis:

Retrosynthesis is the process of deconstructing a target molecule into reality available starting material by means of imaginary breaking bonds (disconnection) and the conversion of one functional group into another functional group.

Disconnection:

An analytical operation by which breaks a bond and converts a molecule into a possible starting material.

Enamine formation:

When a secondary amine react with carbonyl compounds, its form enamine.

Like imine formation, the formation of an enamine also required acid catalyzed for the removal of water molecule.

Acid Catalyzed Hydration Reaction: The reaction involves breaking of $\text{π}$-bonds between carbon-carbon multiple bonds and addition of alcohol to more substituted position of carbon in the molecule.

Acid-catalyzed is generally applied for the removal of water molecule.

Hydrolysis Reaction: This type of reaction involving the braking of a carbon-carbon triple, double bonds in a molecules using water.

Through acid catalyzed process, ketone gets converted into imine.

To predict the reagents used to accomplish the given transformation (a).
