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

${\mathrm{\text{P}}}_2{\mathrm{\text{O}}}_5$is dehydrating agent, hence acid gives anhydrides on dehydration by${\mathrm{\text{P}}}_2{\mathrm{\text{O}}}_5$.

$2\text{R}\mathrm{\text{C}}\mathrm{\text{O}}\mathrm{\text{O}}\mathrm{\text{H}}\underset{-{\mathrm{\text{H}}}_2\mathrm{\text{O}}}{\stackrel{{\mathrm{\text{P}}}_2{\mathrm{\text{O}}}_5}{\to }}{\left(\text{R}\mathrm{\text{C}}\mathrm{\text{O}}\right)}_2\mathrm{\text{O}}$
