Interpretation Introduction

Interpretation:

The given starting compounds and selective reagents used to accomplish the target products transformation should be draw and identified.

Concept introduction:

Addition Reaction: It is defined as chemical reaction in which two given molecules combines and forms product. The types of addition reactions are electrophilic addition, nucleophilic addition, free radical additions and cycloadditions. Generally, compounds with carbon-hetero atom bonds favors addition 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.

H₂/Pt Reduction: The saturated/unsaturated aldehyde and ketones in the presence of hydrogen and Pt the carbonyl compound produced saturated hydrocarbon. In other words the alkene (-C=C-) group involves in the reduction process of H₂/Pt, this end up reducing to give the alkane.

Oxidation Reaction: The oxidation-reduction reaction is a type of chemical reaction it is involves a transfer of electrons between two species. In other words oxidation reaction number of a molecule atom or ion changes by gaining or losing electrons.

Wolff-Kishner Reduction: This type reaction used to convert an aldehyde or ketone to an alkene using hydrazine, base and thermal conditions. The reaction process involves beings with the attack of hydrazine of the aldehyde of ketone for from an corresponding imine.
