Chapter 20, Problem 20.15P

Interpretation Introduction

(a)

Interpretation: The products formed by the treatment of given compound either with ${\text{Ag}}_{\text{2}}{\text{O, NH}}_{\text{4}}\text{OH}$ or ${\text{Na}}_{\text{2}}{\text{Cr}}_{\text{2}}{\text{O}}_{\text{7}}{\text{, H}}_{\text{2}}{\text{SO}}_{\text{4}}{\text{, H}}_{\text{2}}\text{O}$ is to be identified.

Concept introduction: Jones reagent $\left({\text{Na}}_{\text{2}}{\text{Cr}}_{\text{2}}{\text{O}}_{\text{7}}{\text{, H}}_{\text{2}}{\text{SO}}_{\text{4}}{\text{, H}}_{\text{2}}\text{O}\right)$ is an oxidizing agent. It oxidizes aldehyde to carboxylic acid, primary alcohols to carboxylic acid and secondary alcohols to ketones. Tollens reagent oxidizes only aldehyde to carboxylic acid.
