IUPAC name of picric acid is :a.) 2,4,6 - Trinitrobenzene carboxylic acidb.) 2,4 - Dinitrobenzene carboxylic acidc.) 2,4,6 - Trinitrophenold.) 2,4 - Dinitrophenol
Picric acid is a well-known compound with the IUPAC name 2,4,6-trinitrophenol. Here's how you determine this:
Identify the base structure: Picric acid is a derivative of phenol (which is a benzene ring with an -OH group).
Identify the substituents: The molecule has three nitro groups (-NO₂) attached to the benzene ring.
Determine the positions: The nitro groups are positioned at the 2, 4, and 6 positions relative to the hydroxyl group on the benzene ring.
Name the compound:
The base structure is phenol.
The presence of three nitro groups in positions 2, 4, and 6 makes it "trinitrophenol."
So, the correct answer is c.) 2,4,6 - Trinitrophenol.
