Interpretation Introduction

Interpretation:

The target molecule transformation should be drawn and identified for the given corresponding starting molecules by using its structures.

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.

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

Grignard Reaction: This is a organometallic reaction in different alkyl, aryl-magnesium halides add to a carbonyl group in an aldehyde and ketone. This reaction is an important for the conversion of carbon-carbon single (-C-C-) bond. Moreover the addition of a reagent to an aster, lactone gives a tertiary alcohol in which will alkyl groups are the same and the addition of a Grignard reagent to a nitrile produces an unsymmetrical ketone.

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