Question

The major product of the acetylation of salicylic acid with $A{c_2}\dfrac{O}{{{H^ + }}}$ followed by heating with anhydrous $AlC{l_3}$ is:
A.
B.

C.

D.

Answer 1

The acetylation of salicylic acid is an electrophilic reaction. This reaction occurs in the presence of a catalyst. This reaction is subjected to acetylation and the given product is acetic acid as the final product. An electron pair replaces the functional group. The three steps involved in the electrophilic substitution reaction. Acetylation introduced by acetyl group.

Complete step by step answer:
Acetylation of salicylic acid forms aspirin in acidic medium. Acetic anhydride interacts with salicylic acid in presence of conc. Sulphury acid for production of aspirin and given product of acetic acid. Acetylation of salicylic acid is electrophilic reaction. This reaction occurs in the presence of $A{c_2}O$ .
The synthesis of acetylation of salicylic acid is given below:

As we see the acetylation of salicylic acid gives us products of acetylsalicylic acid.

Therefore, Option (A) is the correct answer.

Additional information:
It is used for minor aches and mild to moderate pain which is recommended for arthritic conditions. It reduces risk of transient ischemic attacks in men. In organic chemistry, electrophile reaction in a chemical compound, the bond is broken and two new bonds are formed.

Note: In this reaction electron substitution reaction takes place. Here we remember how bond breaks and new bonds formed. The reaction takes place in the presence of a catalyst. Now we try to understand the formation of the product. There are acetic acid and aspirin given to us as products.
