Ethanoyl chloride reacts with ethanol to give
Correct answer: A. ethyl ethanoate and hydrogen chloride
- A. ethyl ethanoate and hydrogen chloride
- B. ethanoic acid and chlorine
- C. ethane and water
- D. ethanal and hydrogen chloride
Explanation
The alcohol attacks the carbonyl carbon and chloride is expelled, giving the ester rapidly and irreversibly along with fumes of hydrogen chloride. This route is preferred over direct esterification when a high yield is needed, since no equilibrium limits it. The vigorous reaction with water is the reason acyl chlorides must be kept dry.

About Carboxylic Acid Derivatives
Carboxylic acid derivatives include acid halides, acid anhydrides, esters and amides, formed by replacing the hydroxyl group of a carboxylic acid. Their nomenclature, structures, preparation, hydrolysis and relative reactivity are linked through nucleophilic acyl substitution, which differs from the nucleophilic addition reactions of aldehydes and ketones.
