When ethanol is warmed with ethanoic acid in the presence of strong acid catalyst, an ester ethyl ethanoate is formed.CH3CH2OH + CH3CO2H ⟶ CH3CO2CH2CH3 During this reaction:
Correct answer: C. O-H bond in ethanol is broken
- A. Alcohol is reduced
- B. O-H bond in ethanoic acid is broken
- C. O-H bond in ethanol is broken
- D. Acid is oxidized
Explanation
SN reaction of alcohol. O-H bond of alcohol breaks and electrophilic portion of acid combines with O of alcohol.

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.
