Chapter 23, Problem 43A

a)

Interpretation Introduction

Interpretation: To write the expected product that is obtained by the given reactions.

Concept Introduction: Oxidation reactions involve the transfer of elements between two elements. The oxidation number of an atom or an ion gets changed during the oxidation reaction. Oxidation is also referred to as the reaction of gaining oxygen.

Answer to Problem 43A

  

Explanation of Solution

In the given reaction the primary alcohols are converted to aldehydes. The conversion of primary alcohols takes place in the presence of oxidizing agents like ${\text{K}}_{\text{2}}{\text{Cr}}_{\text{2}}{\text{O}}_{\text{7}}$ in the presence of an acidic medium. Under these conditions, primary alcohols are oxidized to aldehydes.

Answer to Problem 43A

  

Explanation of Solution

In the given reactions, aldehydes are converted to carboxylic acids. The conversion of these aldehydes will take place in the presence of ${\text{K}}_{\text{2}}{\text{Cr}}_{\text{2}}{\text{O}}_{\text{7}}$ in the presence of an acidic medium. Under these conditions, aldehydes are converted to carboxylic acids.

Answer to Problem 43A

  

Explanation of Solution

In the given reaction, the alcohol is given as the secondary alcohol. The oxidation of the secondary alcohol in the presence of ${\text{K}}_{\text{2}}{\text{Cr}}_{\text{2}}{\text{O}}_{\text{7}}$ in the presence of acidic medium will result in the production of butan-2-one. Under these conditions, the secondary alcohols are converted to ketones.
