Interpretation Introduction

Interpretation: The reagents used to achieve the given transformation should be 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.

Anti-Markovnikov’s Addition Rule: The unsymmetrical alkene in a chemical compound reacts with hydrogen halide in a way, where halide ions attacks and bond to the less substitution position of carbon-carbon double bond.

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

Radical Bromination: It is a type of bromination which proceeds via radical chain mechanism.

Radical or free radical: unpaired valence electron of an atom, molecule, or ion is called as radical

Hydroboration reaction: The reaction involves addition of ${\text{BH}}_{\text{3}}$ over alkene which attaches ${\text{BH}}_{\text{2}}$ to bond with less substituted position of carbon-carbon double bonds and $\text{H}$ to more substituted position of carbon-carbon double bonds in order to achieve the product with less substitution.

Ozonolysis Reaction: It is an oxidative reaction which is used to oxidise the carbon-carbon double and triple bond.
