Question

What is the IUPAC name of picric acid?

• A. 2-Nitrophenol
• B. 2,4,6-Trinitrophenol
• C. Ethyl Salicylic acid
• D. 2-Aminophenol

Answer 1

The Correct Option is B

Picric acid is the common name for 2,4,6-trinitrophenol.
It is a phenolic compound, meaning it has a hydroxyl group (-OH) attached to a benzene ring.
The name "2,4,6-trinitrophenol" comes from the positions of the nitro groups (NO₂) attached to the benzene ring. The numbers 2, 4, and 6 indicate the positions of the nitro groups, while "phenol" refers to the hydroxyl group attached to the benzene ring.

Thus, 2,4,6-Trinitrophenol is the correct IUPAC name for picric acid.

Answer 2

Picric acid is chemically known as 2,4,6-Trinitrophenol. This compound has three nitro groups (-NO) attached to a benzene ring, giving it highly explosive properties, which is why it was historically used in munitions.
