Chemistry - Carboxylic acid and their Derivatives Question with Solution | TestHub

The alcohol can be converted to aldehyde group by treating with oxidising agent Pyridinium chloro chromate$\left({\mathrm{C}}_5{\mathrm{H}}_5\stackrel{\oplus }{\mathrm{N}}\mathrm{H}\mathrm{C}\mathrm{r}{\mathrm{O}}_3\mathrm{C}{\mathrm{l}}^{-}\right)$it is abbreviated as$\mathrm{P}\mathrm{C}\mathrm{C}$and is called Collin's reagent. This reagent is used in non aqueous solvent like$\mathrm{C}{\mathrm{H}}_2\mathrm{C}{\mathrm{l}}_2$It is a very good reagent because it checks the further oxidation of aldehyde to carboxylic acid while rest oxidising agent oxidise aldehyde into carboxylic acid.
