An organic compound X is prepared by the oxidation of ethanol. This X reacts with ethanol to produce an ester, what is X likely to be:
Correct answer: B. Ethanoic acid
- A. Methanoic acid
- B. Ethanoic acid
- C. Propanoic acid
- D. Butanoic acid
Explanation
The controlled oxidation of ethanol (a two-carbon alcohol) produces ethanoic acid (acetic acid), which is a two-carbon carboxylic acid. Ethanoic acid can then react with ethanol in an esterification reaction to form an ester (ethyl acetate).

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
