Chapter 10, Problem 10.50P

Interpretation Introduction

(a)

Interpretation: The product formed when cyclohexene reacts with given reagent is to be drawn.

Concept introduction: Hydrogen bromide reacts with an alkene to form an alkyl bromide. The reaction is known as hydrohalogenation. A general hydrohalogenation reaction is represented as,

$\text{R}=\text{R}+\text{HBr}\to \text{HR}-\text{RBr}$

Interpretation Introduction

(b)

Interpretation: The product formed when cyclohexene reacts with given reagent is to be drawn.

Concept introduction: Hydrogen iodide reacts with an alkene to form an alkyl iodide. The reaction is known as hydrohalogenation. A general hydrohalogenation reaction is represented as,

$\text{R}=\text{R}+\text{HI}\to \text{HR}-\text{RI}$

Interpretation Introduction

(c)

Interpretation: The product formed when cyclohexene reacts with given reagent is to be drawn.

Concept introduction: Sulfuric acid is a strong acid. Sulfuric acid is used in any acid catalyst reaction. It easily gives its proton that is used to precede the reaction. Alkenes react with water in the presence of sulfuric acid to form alcohol.

Interpretation Introduction

(d)

Interpretation: The product formed when cyclohexene reacts with given reagent is to be drawn.

Concept introduction: Sulfuric acid is a strong acid. Sulfuric acid is used in any acid catalyst reaction. It easily gives its proton that is used to precede the reaction. Alkenes react with alcohol in the presence of sulfuric acid to form ether.

Interpretation Introduction

(e)

Interpretation: The product formed when cyclohexene reacts with given reagent is to be drawn.

Concept introduction: Chlorine gas reacts with an alkene to form a dichloroalkane. The reaction is known as halogenation. A general halogenation reaction is represented as,

$\text{R}=\text{R}+{\text{Cl}}_2\to \text{ClR}-\text{RCl}$

Interpretation Introduction

(f)

Interpretation: The product formed when cyclohexene reacts with given reagent is to be drawn.

Concept introduction: Bromine water reacts with an alkene in the presence of water to form a bromine substituted alcohol. The reaction is known as halohydrin reaction. A general halohydrin reaction is represented as,

$\text{R}=\text{R}+{\text{Br}}_2\to \text{HOR}-\text{RBr}$

Interpretation Introduction

(g)

Interpretation: The product formed when cyclohexene reacts with given reagent is to be drawn.

Concept introduction: The reagent $\text{N}-\text{Bromosuccinimide}$ is used for bromine addition in an organic compound. When $\text{N}-\text{Bromosuccinimide}$ dissolved in aqueous DMSO is reacted with an alkene, it undergo a halohydrin reaction.

Interpretation Introduction

(h)

Interpretation: The product formed when cyclohexene reacts with given reagent is to be drawn.

Concept introduction: In hydroboration reaction of alkenes, alkenes react with ${\text{BH}}_{\text{3}}$ and then get oxidized by hydrogen peroxide to form an alcohol.

Hydrogen peroxide is a good an oxidizing agent.

Interpretation Introduction

(i)

Interpretation: The product formed when cyclohexene reacts with given reagent is to be drawn.

Concept introduction: The reagent $\text{9}-\text{Borabicyclo(3}\text{.3}\text{.1)nonane}$ also known as $\text{9-BB}\text{}\text{N}$, undergoes hydroboration with alkene to form alcohol. Hydrogen peroxide is used as oxidizing agent in this hydroboration reaction.
