Chapter 22.4, Problem 19SSC

Interpretation Introduction

(a)

Interpretation:

The type of organic reaction needs to be identified.

$\text{alkyl halide}\to \text{alkene}$

Concept introduction:

The functional group is the group present on the main carbon chain of an organic compound. It determines the chemical properties and the type of reactions an organic compound can show.

Answer to Problem 19SSC

Elimination reaction.

Explanation of Solution

The given reaction is as follows:

$\text{alkyl halide}\to \text{alkene}$

In the above reaction, halide group and the hydrogen atom present at the adjacent carbon to it gets eliminated to form an alkene.

Since, in this reaction HX (where X is halide group) gets eliminated, it is an elimination reaction.

Interpretation Introduction

(b)

Interpretation:

The type of organic reaction needs to be identified.

$\text{alkene}\to \text{alcohol}$

Concept introduction:

The functional group is the group present on the main carbon chain of an organic compound. It determines the chemical properties and the type of reactions an organic compound can show.

Answer to Problem 19SSC

Hydration reaction.

Explanation of Solution

The given reaction is as follows:

$\text{alkene}\to \text{alcohol}$

Here, water is added to an alkene to form alcohol. This is a hydration reaction because in this reaction water molecule is added to a compound to form a new compound. Therefore, this is a hydration reaction.

Interpretation Introduction

(c)

Interpretation:

The type of organic reaction needs to be identified.

$\text{alcohol}+\text{carboxylic acid}\to \text{ester}$

Concept introduction:

The functional group is the group present on the main carbon chain of an organic compound. It determines the chemical properties and the type of reactions an organic compound can show.

Answer to Problem 19SSC

Esterification reaction.

Explanation of Solution

The given reaction is as follows:

$\text{alcohol}+\text{carboxylic acid}\to \text{ester}$

In the above reaction, alcohol reacts with carboxylic acid to form ester thus, it is an esterification reaction.

Interpretation Introduction

(c)

Interpretation:

The type of organic reaction needs to be identified.

$\text{alkene}\to \text{alkyl dihalide}$

Concept introduction:

The functional group is the group present on the main carbon chain of an organic compound. It determines the chemical properties and the type of reactions an organic compound can show.

Answer to Problem 19SSC

Halogenations reaction.

Explanation of Solution

The given reaction is as follows:

$\text{alkene}\to \text{alkyl dihalide}$

In the above reaction, aklene reacts with dihalide to form alkyldihalide. In this reaction addition of dihalide takes place to alkene molecule. Since, addition of halogen is taking place, it is known as halogenation reaction.
