What is the primary organic product when 1-propanol undergoes controlled oxidation with pyridinium chlorochromate (PCC) in anhydrous dichloromethane?
Answer and explanation
Correct answer: D. Propanal (aldehyde)
- Step 1: Identify reactant: 1-propanol is a primary alcohol ().
- Step 2: Determine reagent: PCC is a mild oxidizing agent that selectively oxidizes primary alcohols to aldehydes without further oxidation to carboxylic acids.
- Step 3: Product structure: (propanal).
Answer
Propanal (aldehyde).
Why not the others: 'Propanoic acid' is formed by strong oxidizers like or ; 'Propanone' is formed from secondary alcohol (2-propanol); 'Propyl propanoate' is an ester formed by esterification.
