Question

Aspirin is obtained by the reaction of acetyl chloride with
(A) Ethanol
(B) Phenol
(C) Salicylic acid
(D) Benzoic acid

Answer 1

We know that aspirin is also known as acetylsalicylic acid . Aspirin is a very important compound which is used to make many medicines. The molecular formula of aspirin is ${C_9}{H_8}{O_4}$. Aspirin is used as an analgesic .

Complete step by step answer:
As we know that the aspirin is formed by a special type of reaction known as esterification reaction. Acetyl chloride is a very reactive compound. Acetyl chloride reacts with Salicylic acid vigorously in the presence of pyridine to form acetylsalicylic acid or the aspirin . Pyridine is used in the reaction because the nitrogen in the pyridine is a nucleophilic catalyst. Aspirin can also be formed by the reaction of salicylic acid and acetic anhydride. So from the above explanation it is clear that aspirin is formed by the reaction of acetyl chloride and salicylic acid.

Fig: Aspirin or acetylsalicylic acid

So the correct answer of the question is : (C) Salicylic acid

Additional information:
Aspirin or acetylsalicylic acid is used to cure pain, fever and inflammation. Aspirin is a non narcotic drug. It is used as a painkiller. Aspirin is also used to cure rheumatoid arthritis, pericarditis, and Kawasaki disease. Some examples of narcotic drugs are codeine , morphine and heroin. Non narcotic drugs are offered as non prescription drugs.

Note:
Always remember that aspirin is formed by the esterification reaction. Acetyl chloride reacts with salicylic acid in the presence of pyridine to form aspirin. Aspirin is also known as acetylsalicylic acid. It is a non narcotic drug which is used to cure many diseases .
