Which of the following chemical reactions correctly pair the starting alcohol and oxidizing agent wi — Alcohols Phenols and Ethers Chemistry Question

💡 Solution & Explanation

PCC is a mild oxidizing agent that stops the oxidation of primary alcohols at the aldehyde stage (propanal). Secondary alcohols (propan-2-ol) are oxidized to ketones (propanone) by strong agents like dichromate. Primary alcohols (ethanol) are fully oxidized to carboxylic acids (ethanoic acid) by strong $KMnO_4$. Statement C is incorrect; tertiary alcohols resist oxidation under neutral/mild conditions at room temperature.
