Interpretation Introduction

Interpretation:

The plausible reaction and mechanism should be draw and identified for the given set of molecules under acid-catalyst conditions ( $H^{+}/Et-OH$).

Concept introduction:

Nucleophiles: A nucleophile is a more reactant species that affords a pair of electrons to the electrophile or electrophilic center and forms a new covalent bond. The carbon or other hetero atom in a molecule which is bearing negative charge or lone pair of electron is called as nucleophiles.

Electrophile: An electrophile is a species that accepts a pair of electrons to form a new covalent bond.

Nucleophilic reaction: electron rich nucleophiles attack the positive or partially positive charge of an atom and replace a leaving group is called Nucleophilic Substitution reaction.

Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via E1 (the reaction depends only on the substrate involved in the reaction) or E2 (the reaction depends on both of the substituents in the reaction) mechanism.

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

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.

To identify: The synthetic route to accomplish the given transformation.
