Chapter 11, Problem 42P

(a)

Interpretation Introduction

Interpretation:

The reagent has to be identified for the conversion of methyl propanoate to the following compounds.

Concept introduction:

A reagent is a substance used to convert one chemical compound into another.

Transesterification: Transesterification reaction is an esterification reaction of ester react with excess of alcohol in the presence of either acid or base catalyst to form a new ester. The formation of one type of ester can be transformed in to other form of esters is called esterification when reaction moves forward when we use excess of an alcohol.

    

(b)

Interpretation Introduction

Interpretation:

The reagent has to be identified for the conversion of methyl propanoate to the following compounds.

Concept introduction:

Ester reaction with sodium hydroxide which goves the sodium salt and alcohol.

It is an example of saponification reaction.

(c)

Interpretation Introduction

Interpretation:

The reagent has to be identified for the conversion of methyl propanoate to the following compounds.

Concept introduction:

Amination reaction: Amination is the process by which an amine group is introduced into an organic molecule.

(d)

Interpretation Introduction

Interpretation:

The reagent has to be identified for the conversion of methyl propanoate to the following compounds.

Concept introduction:

Ester reaction with sodium hydroxide which gives the sodium salt and alcohol this sodium salt further reaction with dil. Hydrochloric acid gives acid.

It is an example of saponification reaction.
