Interpretation Introduction

(a)

Interpretation: The carbonyl compound formed when the given alcohol is treated with ${\text{HCrO}}_4^{-}\text{-Amberlyst}\text{A-}26$ resin is to be predicted.

Concept introduction: ${\text{HCrO}}_4^{-}\text{-Amberlyst}\text{A-}26$ is an insoluble polymeric reagent. It consists of complex hydrocarbon network with cationic ammonium ion which acts a counter ion to anionic chromium ion. This is a green chemistry method for oxidation of alcohols as it avoids the usage of strong acids and also it forms by-product with carcinogenic ${\text{Cr}}^{3+}$ which can be removed by filtration.
