Question

Salicylic acid, HOC₆H₄CO₂H, and its derivatives have been used as pain relievers for a long time. Salicylic acid occurs in small amounts in the leaves, bark, and roots of some vegetation (most notably historically in the bark of the willow tree). Extracts of these plants have been used as medications for centuries. The acid was first isolated in the laboratory in:

a) 1838
b) 1874
c) 1902
d) 1765

Answer 1

Salicylic acid was first isolated in the lab in 1838. It is used in medicine, and aspirin, or acetylsalicylic acid, is a derivative known for being less irritating to the stomach. option (A)

Step-by-step explanation:

Salicylic acid, HOC₆H₄CO₂H, and its derivatives such as aspirin, have been widely used for their medicinal properties, such as pain relief, fever reduction, and anti-inflammatory effects. Salicylic acid was first isolated in the laboratory in 1838.

Aspirin, also known as acetylsalicylic acid, is an ester of salicylic acid made from the bark of the willow tree that overcomes the stomach irritation commonly associated with salicylic acid. The discovery of aspirin can be traced back to the efforts to improve upon the natural properties of salicylic acid and has been a staple of medicine for over a century.
