Question

Which of the following reagents is the most suitable mild oxidizing agent to convert 1-pentanol to pentanal while preventing further oxidation to pentanoic acid?

Answer: C

💡 Solution & Explanation

Strong oxidizing agents like acidified $K_2Cr_2O_7$, $KMnO_4$, and aqueous $CrO_3$ will further oxidize the resulting aldehyde into a carboxylic acid. Pyridinium chlorochromate (PCC) in an anhydrous solvent like $CH_2Cl_2$ is a mild, selective oxidizing agent that halts the oxidation exactly at the aldehyde stage.
