What functional group is produced when a primary alcohol is fully oxidized using an acidified potassium dichromate solution?
Answer and explanation
Correct answer: B. Carboxylic acid
- Step 1: Primary alcohols () are first oxidized to aldehydes ().
- Step 2: Under prolonged reflux with strong oxidizing agents like acidified dichromate, aldehydes are further oxidized to carboxylic acids ().
Answer
Carboxylic acid.
Why not the others: 'Ketone' is produced by oxidizing secondary alcohols; 'Ester' is formed by condensation of alcohol and carboxylic acid; 'Ether' is formed by dehydration of alcohols.
