Here's how you can prepare a named aldehyde and a named ketone using the oxidation of alcohols: 1. Preparation of a named aldehyde (e.g., Propanal) Aldehydes are prepared by the mild oxidation of a primary alcohol. It's crucial to use a mild oxidizing agent to prevent further oxidation of the aldehyde to a carboxylic acid. Step 1: Choose a primary alcohol. Let's use propan-1-ol. CH_3CH_2CH_2OH (Propan-1-ol) Step 2: Choose a mild oxidizing agent. Pyridinium chlorochromate (PCC) is a common reagent for this transformation. Step 3: Perform the oxidation. When propan-1-ol is oxidized with PCC in dichloromethane (CH_2Cl_2), it yields propanal. CH_3CH_2CH_2OH PCC, CH_2Cl_2 CH_3CH_2CHO The named aldehyde prepared is Propanal. 2. Preparation of a named ketone (e.g., Propanone) Ketones are prepared by the oxidation of a secondary alcohol. Stronger oxidizing agents can be used here because ketones are generally resistant to further oxidation under these conditions. Step 1: Choose a secondary alcohol. Let's use propan-2-ol. CH_3CH(OH)CH_3 (Propan-2-ol) Step 2: Choose an oxidizing agent. Chromic acid (H_2CrO_4, often formed in situ from Na_2Cr_2O_7 or K_2Cr_2O_7 in H_2SO_4) is a common reagent. PCC can also be used. Step 3: Perform the oxidation. When propan-2-ol is oxidized with chromic acid, it yields propanone. CH_3CH(OH)CH_3 H_2CrO_4 CH_3COCH_3 The named ketone prepared is Propanone.
