Aspirin is an acetylation product of ______ ? (1) p-dihydroxybenzene. (2) o-hydroxybenzoic acid. (3) o-dihydroxybenzene. (4) m-hydroxybenzoic acid.

Question : Aspirin is an acetylation product of ______ ?

(1) p-dihydroxybenzene.

(2) o-hydroxybenzoic acid.

(3) o-dihydroxybenzene.

(4) m-hydroxybenzoic acid.

Answer : In all above four options the correct answer is “(2) o-hydroxybenzoic acid. ”

Explanation of answer : When acetylation reaction happed with o-Hydroxybenzoic acid than after the acetylation reaction the 2-acetoxybenzoic acid product is resultant , and the resultant product named 2-acetoxybenzoic acid is also called by name aspirin.

The acetylation reaction of  o-hydroxybenzoic acid is shown in figure below –

 

that why the correct of question Aspirin is an acetylation product of ______ ?  is  (2) o-Hydroxybenzoic acid on acetylation gives aspirin.
